Introduction

Semiconductor manufacturing often feels like modern alchemy: billions of tiny transistors squeezed onto a chip smaller than a fingernail, stitched through thousands of precise steps. Shifting a line by nanometres can ruin the batch.

The stakes are enormous. One day of unplanned downtime in a top fab can wipe out over $20 million. Problems aren’t always dramatic shutdowns; sometimes, process drift quietly eats into yields, totalling billions in lost revenue yearly. Factor in easily wobbling supply chains, and you see the industry’s looming “trillion-dollar risk.”

AI-powered digital twins are living mirrors of the factory. Continuously updated with real data, they run endless “what-if” scenarios, catching errors before they become costly. It’s like rehearsing production virtually, avoiding real-world mistakes.

1. What is a Digital Twin in Semiconductor Manufacturing?

Now, a digital twin in a fab isn’t just some fancy simulation it’s basically a virtual twin of the whole facility, kept in lockstep with the real thing. Traditional simulations? They’re kind of frozen in time. Digital twins, on the other hand, are always moving, always learning, pulling in data from thousands of sensors, tool logs, and manufacturing systems to really reflect what’s happening on the floor.

Their scope is huge. For instance:

• Wafer Fab Scheduling: Figuring out the best sequence and queue times across hundreds of tools, shaving days off wafer cycles that can otherwise drag past 90 days.
• Tool Behavior Simulation: Watching how lithography, etching, and deposition tools drift or wear out, and guessing when they’ll need attention.
• Predictive Maintenance: Catching potential failures before they hit, avoiding downtime that could grind production to a halt.

The cool part? They keep getting smarter. Every wafer that runs through the fab teaches the twin a little more, helping it predict better and suggest fixes before things go sideways. Over time, fabs move from constantly reacting to actually staying ahead of the game.

2. How AI Makes Digital Twins Smarter

AI is the real power that changes things. Digital twins transition from mere reflections to autonomous control systems capable of independent decision-making.

For instance:

• Defect Prediction: Machine learning spots tiny defect patterns humans or simple rules miss. A lithography misalignment, for instance, is caught before it ruins wafers.
• Automated Calibration: Reinforcement learning algorithms fine-tune deposition or etch times, keeping precision high with minimal human input.
• Fab Simulation: You can stress-test entire fabs virtually (temperature, vibration, purity changes) to see how production fares.

The impact is real:

• 30% faster validation, qualifying new processes quicker.
• 25% better yield forecasts, cutting waste.
• Avoided downtime over $2 million per tool daily (SEMI data).

AI tools like Bayesian models and reinforcement learning push fabs toward self-regulation—the factory learns to heal itself. The workflow below shows how AI twins turn raw data into better supply chain outcomes.

 

Figure 1: AI-powered digital twins connect fab data, predictive analytics, and real-time simulation to deliver measurable gains in yield, procurement efficiency, and supply chain resilience.

3. Procurement & Supply Chain Resilience

The engineering benefits of digital twins are clear, but they also bring unexpected value to procurement and supply chain planning, functions exposed as fragile during the pandemic-era chip shortage.

• Supplier Qualification: Before approving new photoresists, gases, or wafers, digital twins simulate their impact on yield, reducing the risk of supplier-induced disruptions.
• Equipment Sourcing: AI predicts the saturation point of tools, enabling fabs to place orders in advance and avoid expensive overstocking.
• Virtual Commissioning: Tools can be simulated in the digital twin prior to acquisition, guaranteeing return on investment and compatibility with current production lines.

Case Study: When advanced lithography tools ran short in 2021, a major foundry used its twin to re-sequence wafer queues. This move held throughput steady, saved nearly $5 million in delay costs, and kept chips on schedule.

The globalization of supply chains necessitates this foresight. A firm in Taiwan can now anticipate the effects of a European chemical delay weeks in advance and adjust wafer production schedules to mitigate losses.

4. Future Outlook: Virtual Fabs, Resilience, and ESG

The goal is the “virtual-first fab.” Every new process or recipe must be fully tested in the twin before going live. That method sharply lowers risk and cuts the cost of old-school trial-and-error.

Beyond efficiency, twins are crucial for sustainability targets:

• Scrap: Less wafer loss helps factories cut material scrap by 5–10%.
• Energy: Better tuning and scheduling can drop energy use by 3–7% per wafer.
• Waste: Fewer reworks directly cuts chemical and water usage.

Rahimian and other experts say that smart fabs of the future will combine efficiency with resilience, making supply chains stronger and better for the environment.

5. Challenges on the Road Ahead

Despite their promise, setting up and maintaining a digital twin system is tough.

• Data Silos: Merging data from specialized, unlike tools is the core issue. Many factories use older equipment that lacks common data formats.
• Computational Demands: Running high-fidelity twins needs exascale computing, which smaller operations can’t afford.
• Adoption Hurdles: The industry needs simple rules for interoperability. Plus, veteran engineers must trust AI over their experience.

Solving this requires equipment makers, software firms, and chip producers to collaborate. Groups like SEMI are already pushing for common standards.

6. Visualizing the Future

To see the full potential, think of a digital dashboard for a modern fab operator:

A heatmap shows when the wafer queue will be full, so there is no chaos.  3D models forecast tool wear weeks in advance. A supply chain radar tracks every bottleneck like a neon shortage or logistics delay in real time.

These visuals change factories from reactive spaces to proactive ecosystems. Every worker can now anticipate and adapt to changes, instead of constantly fighting crises.

Conclusion

The semiconductor industry drives nearly every modern device, yet its manufacturing risks are enormous. Digital twins are becoming essential because they let engineers spot yield problems early, see where supply issues may emerge, and keep sustainability efforts on track. These models aren’t just virtual copies of factories; they give teams clearer insight into how to run tools, materials, and workflows more efficiently and with fewer surprises. As digital-twin technology matures, it’s set to influence how leading fabs plan, test, and refine production. The message is clear: manufacturing’s future isn’t only physical. It’s virtual-first, AI-validated, and designed to prevent trillion-dollar mistakes.

Melexis introduces a 16-bit inductive sensor for robotics, industrial, and mobility applications. The new dual-input MLX90514 delivers absolute position with high noise immunity through its SSI output protocol.

Applications such as robotic joint control, industrial motor commutation, and e-mobility drive systems require sensors with high-precision feedback, compact form factor, low-latency response, resilience to environmental stressors, and seamless integration, Melexis explained.

These sensors also need to overcome the limitations of optical encoders and magnetic-based solutions, the company said, which the MLX90514 addresses with its contactless inductive measurement principle. This results in stable and repeatable performance in demanding operational environments.

The inductive measurement principle operates without a permanent magnet, reducing design effort, and the sensor’s PCB-based coil design simplifies assembly and reduces costs, Melexis added.

In addition, the sensor is robust against dust, mechanical wear, and contamination compared with optical solutions. The operating temperature ranges from ‐40°C to 160°C.

(Source: Melexis)

The inductive sensor’s dual-input architecture simultaneously processes signals from two coil sets to compute vernier angles on-chip. This architecture consolidates position sensing in a single IC, reducing external circuitry and enhancing accuracy.

The MLX90514 also ensures synchronized measurements, and supports enhanced functional safety for applications such as measuring both input and output positions of a motor in e-bikes, motorcycles, or robotic joints, according to the company.

Targeting both absolute rotary or linear motion sensing, the MLX90514 provides up to 16-bit position resolution and zero-latency measurement with accuracy better than 0.1° for precise control in demanding environments. Other features include a 5-V supply voltage, coil diameters ranging from 20 mm to 300 mm, and linear displacements of up to 400 mm.

The inductive sensor offers plug-and-play configuration. Engineers only need to program a limited set of parameters, specifically offset compensation and linearization, for faster system integration.

The MLX90514 inductive sensor interface IC is available now. Melexis offers a free online Inductive Simulator tool, which allows users to design and optimize coil layouts for the MLX90514.

Peripheral Component Interconnect Express, or PCI Express (PCIe), is a widely used bus interconnect interface, found in servers and, increasingly, as a storage and GPU interconnect solution. The first version of PCIe was introduced in 2003 by the Peripheral Component Interconnect Special Interest Group (PCI-SIG) as PCIe Gen 1.1. It was created to replace the original parallel communications bus, PCI.

With PCI, data is transmitted at the same time across many wires. The host and all connected devices share the same signals for communication; thus, multiple devices share a common set of address, data, and control lines and clearly vie for the same bandwidth.

With PCIe, however, communication is serial point-to-point, with data being sent over dedicated lines to devices, enabling bigger bandwidths and faster data transfer. Signals are transferred over connection pairs, known as lanes—one for transmitting data, the other for receiving it. Most systems normally use 16 lanes, but PCIe is scalable, allowing up to 64 lanes or more in a system.

The PCIe standard continues to evolve, doubling the data transfer rate per generation. The latest is PCIe Gen 7, with 128 GT/s per lane in each direction, meeting the needs of data-intensive applications such as hyperscale data centers, high-performance computing (HPC), AI/ML, and cloud computing.

PCIe clocking

Another differentiating factor between PCI and PCIe is the clocking. PCI uses LVCMOS clocks, whereas PCIe uses differential high-speed current-steering logic (HCSL) and low-power HCSL clocks. These are configured with the spread-spectrum clocking (SSC) scheme.

SSC works by spreading the clock signal across several frequencies rather than concentrating it at a single peak frequency. This eliminates large electromagnetic spikes at specific frequencies that could cause interference (EMI) to other components. The spreading over several frequencies reduces EMI, which protects signal integrity.

On the flip side, SSC introduces jitter (timing variations in the clock signal) due to frequency-modulating the clock signal in this scheme. To preserve signal integrity, PCIe devices are permitted a degree of jitter.

In PCIe systems, there’s a reference clock (REFCLK), typically a 100-MHz HCSL clock, as a common timing reference for all devices on the bus. In the SSC scheme, the REFCLK signal is modulated with a low-frequency (30- to 33-kHz) sinusoidal signal.

To best balance design performance, complexity, and cost, but also to ensure best functionality, different PCIe clocking architectures are used. These are common clock (CC), common clock with spread (CCS), separate reference clock with no spread (SRNS), and separate reference clock with independent spread (SRIS). Both CC and separate reference architectures can use SSC but with a differing amount of modulation (for the spread).

Each clocking scheme has its own advantages and disadvantages when it comes to jitter and transmission complexity. The CC is the simplest and cheapest option to use in designs. Here, both the transmitter and receiver share the same REFCLK and are clocked by the same PLL, which multiplies the REFCLK frequency to create the high-speed clock signals needed for the data transmission. With the separate clocking scheme, each PCIe endpoint and root complex have their own independent clock source.

PCIe switches

To manage the data traffic on the lanes between different components within a system, PCIe switches are used. They allow multiple PCIe devices, from network and storage cards to graphics and sound cards, to communicate with one another and the CPU simultaneously, optimizing system performance. In cloud computing and AI data centers, PCIe switches connect multiple NICs, GPUs, CPUs, NPUs, and other processors in the servers, all of which require a robust and improved PCIe infrastructure.

PCIe switches play a key role in next-generation open, hyperscale data center specifications now being worked on rapidly by a growing developer contingent around the world. This is particularly needed with the advent of ML- and AI-centric data centers, underpinned by HPC systems. PCIe switches are also instrumental in many industrial setups, wired networking, communications systems, and where many high-speed devices must be connected with data traffic managed effectively.

A well-known brand of PCIe switches is the Switchtec family from Microchip Technology. The Switchtec PCIe switch IP manages the data flow and peer-to-peer transfers between ports, providing flexibility, scalability, and configurability in connecting multiple devices.

The Switchtec Gen 5.0 PCIe high-performance product lineup delivers very low system latency, as well as advanced diagnostics and debugging tools for troubleshooting and fast product development, making it highly suitable for next-generation data center, ML, automotive, communications, defense, and industrial applications, as well as other sectors. Tier 1 data center providers are relying on Switchtec PCIe switches to enable highly flexible compute and storage rack architectures.

Reference design and evaluation kit for PCIe switches

To enable rapid, PCIe-based system development, Microchip has created a validation board reference design, shown in Figure 1, using the Switchtec Gen 5 PCIe Switch Evaluation Kit, known as the PM52100-KIT.

Figure 1: Microchip’s Switchtec Gen 5 PCIe switch reference design validation board (Source: Microchip Technology Inc.)

The reference design helps developers implement the Switchtec Gen 5 PCIe switch into their own systems. The guidelines show designers how to connect and configure the switch and how to reach the best balance for signal integrity and power, as well as meet other critical design aspects of their application.

Fully tested and validated, the reference design streamlines development and speeds time to market. The solution optimizes performance, costs, and board footprint and reduces design risk, enabling fast market entry with a finished product. See the solutions diagram in Figure 2.

Figure 2: Switchtec Gen 5 PCIe solutions setup with other key devices (Source: Microchip Technology Inc.)

As with all Switchtec PCIe switch designs, full access to the Microchip ChipLink diagnostics tool is included, which allows parameter configuration, functional debug, and signal integrity analysis.

As per all PCIe integrations, clock and timing are important aspects of the design. Clock solutions must be highly reliable for demanding end applications, and the Microchip reference design includes complete PCIe Gen 1–5 timing solutions that include the clock generators, buffers, oscillators, and crystals.

Microchip’s ClockWorks Configurator and product selection tool allow easy customization of the timing devices for any application. The tool is used to configure oscillators and clock generators with specific frequencies, among other parameters, for use within the reference design.

The Microchip PM52100-KIT

For firsthand experience of the Switchtec Gen 5 PCIe switch, Microchip provides the PM52100-KIT (Figure 3), a physical board with 52 ports. The kit enables users to experiment with and evaluate the Switchtec family of Gen 5 PCIe switches in real-life projects. The kit was built with the guidance provided by the Microchip reference design.

Figure 3: The Microchip PM52100-KIT (Source: Microchip Technology Inc.)

The kit contains an evaluation board with the necessary firmware and cables. Users can download the ChipLink diagnostic tool by requesting access via a myMicrochip account.

With the ChipLink GUI, which is suitable for Windows, Mac, or Linux systems, the board’s hardware functions can easily be accessed and system status information monitored. It also allows access to the registers in the PCIe switch and configuration of the high-speed analog settings for signal integrity evaluation. The ChipLink diagnostic tool features advanced debug capabilities that will simplify overall system development.

The kit operates with a PCIe host and supports the connection of multiple host entities to multiple endpoint devices.

The PCIe interface contains an edge connector for linking to the host, several PCIe Amphenol Mini Cool Edge I/O connectors to connect the host to endpoints, and connectors for add-in cards. The 0.60-mm Amphenol connector allows high-speed signals to Gen 6 PCIe and 64G PAM4/PCIe, but also Gen 5 and Gen 4 PCIe. This connector maintains signal integrity, as its design minimizes signal loss and reflections at higher frequencies.

The board’s PCIe clock interface consists of a common reference clock (with or without SSC), SRNS, and SRIS. A single stable clock, with low jitter, is shared by both endpoints. The second most common clocking scheme is SRNS, where an independent clock is supplied to each end of the PCIe link; this is also supported by the Microchip kit.

Among the kit’s peripherals are two-wire (TWI)/SMBus interfaces; TWI bus access and connectivity to the temperature sensor, fan controller, voltage monitor, GPIO, and TWI expanders; SEEPROM for storage and PCIe switch configuration; and 100 M/GE Ethernet. The kit also includes GPIOs for TWI, SPI, SGPIO, Ethernet, and UART interfaces. There is UART access with a USB Type-B and three-pin connector header.

The included PSX Software Development Kit (integrating GHS’s MULTI development environment) enables the development and testing of the custom PCIe switch functionalities. An EJTAG debugger supports test and debug of custom PSX firmware; a 14-pin EJTAG connector header allows PSX probe connectivity.

Switchtec Gen 5 52-lane PCIe switch reference design

Microchip also offers a Switchtec 52-lane Gen 5 PCIe Switch Reference Design (Figure 4). As with the other reference design, it is fully validated and tested, and it provides the components and tools necessary to thoroughly assess and integrate this design into your systems.

This board includes a 32-bit microcontroller (ATSAME54, based on the Arm Cortex-M4 processor with a floating-point unit) to be configured with Microchip’s MPLAB Harmony software, as well as a CEC1736 root-of-trust controller. The CEC1736 is a 96-MHz Arm Cortex-M4F controller that is used to detect and provide protection for the PCIe system against failure or malicious attacks.

Editor’s note: In this Design Idea (DI), contributor Bonicatto designs a digital filter system (DFS). This is a benchtop filtering system that can apply various filter types to an incoming signal. The filtering range is up to 120 kHz.

In Part 1 of this DI, the DFS’s function and hardware implementation are discussed.

In Part 2 of this DI, the DFS’s firmware and performance are discussed.

Firmware

The firmware, although a bit large, is not too complicated. It is broken into six files to make browsing the code a bit easier. Let’s start with the code for the LCD screen, and its attached touch detector.

Wow the engineering world with your unique design: Design Ideas Submission Guide

LCD and touchscreen code

Here might be a good place to show the LCD screens, as they will be discussed below.

The LCD screen in the DFS. From the top left: Splash Screen, Main Screen, Filter Selection Screen, Cutoff or Center Frequency Screen, Digital Gain Screen, About Screen, and Running Screen.

A quick discussion of the screens will give you a good overview of the operation and capabilities of the DFS. The first screen is the opening or Splash Screen—not much here to see, but there is a battery charge icon on the upper right.

Touching this screen anywhere will move you to the Main Screen. The Main Screen shows you the current settings and allows you to jump to the appropriate screen to adjust the filter type, cutoff, or center frequency of the filter, and the digital gain. It also has the “RUN” button that starts the filtering function based on the current settings.

If you touch the “Change Filter Type” on the Main Screen, you will jump to the Filter Selection Screen. This lets you select the filter type you would like to use and if you want 2-pole or 4-pole filtering. (Selecting a 2-pole filter will give you a roll-off of 24 dB per octave or 80 dB per decade, while the 4-pole will provide you with a roll-off of 12 dB per octave or 40 dB per decade.) When you touch the “APPLY” button, your settings (in green) will be applied to your filter, and you will jump back to the Main Screen.

In the Main Screen, if you want to change the cutoff/center frequency. You can set any frequency up to 120 kHz. Hitting “Enter” will bring you back to the Main Screen.

If you want to change the digital gain (gain applied when the filter is run on a sample, between the ADC and the DAC, touch “Change Output Gain” on the Main Screen. The range for this gain is from 0.01 to 100. Again, “Enter” will take you back to the Main Screen.

On the Main Screen, selecting “About” will take you to a screen showing lots of interesting information, such as your filter settings, your current filter’s coefficients, battery voltage, and charge level. (If you do not have a battery installed, you may see fully charged numbers as it is seeing the charger voltage. There is a #define at the top of the main code you can set to false if you don’t have a battery installed, and this line won’t show.) The last item shown is the incoming USB voltage.

In the main code, hitting “Run” will start the system to take in your signal at the input BNC, filter it, and send it out the output BNC. The Running Screen also shows you the current filter settings.

Now, let’s take a quick look at the mechanics of creating the screens. The LCD uses a few libraries to assist in the display of primitive shapes and colors, text, and to provide some functions for reading the selected touchscreen position. When opening the Arduino code, you will find a file labeled “TFT_for_adjustable_filter_7.ino”. This file contains the code for most of the screen displays and touchscreen functions. The code is too long to list here, but here are a few lines of code setting the background color and displaying the letters “DFS”:

tft.fillScreen(tft.color565(0xe0, 0xe0, 0xe0)); // Grey tft.setFont(&FreeSansBoldOblique50pt7b); tft.setTextColor(ILI9341_RED); tft.setTextSize(1); tft.setCursor(13, 100); tft.print("DFS");

A lot of the functions look like this, as they are used to present the data and create the keypads for filter selection, frequency setting, and digital gain setting. In this file are also the functions for monitoring and logically connecting the touch to the appropriate function.

The touchscreen, although included on the LCD, is essentially independent from it. One issue that needed to be solved was that the alignment of the touchscreen over the LCD screen is not accurate, and pixel (0,0) is not aligned with the touch position (0,0) on the touchscreen.

Also, the LCD has 240×320 pixels, and the touch screen has, roughly, 3900×900 positions. So there needs to be some calibration and then a conversion function to convert the touch point to the LCD’s pixel coordinates. You’ll see in the code that, after calibration, the conversion function is very easy using the Arduino map() function.

Other files

There is also a file that contains the initialization code for the ADC. This sets up the sample rate, resolution, and other needed items. Note that this is run at the start of the code, but also when changing the number of poles in the filter. This is due to the need to change the sample rate. Another file contains the code to initialize the DAC, and is also called when the program is started.

Also included is a file with code to pull in factory calibration data for linearizing the ADC. This calibration data is created at the factory and is stored in the microcontroller (micro)—nice feature.

Filtering code

Now to the more interesting code. There is code to route you to the screens and their selections, but let’s skip that and look at how the filtering is accomplished. After you have selected a filter type (low-pass, high-pass, band-pass, or band-stop), the number of poles of the filter (2 or 4), the cutoff or center frequency of the filter, or adjusted the internal digital output gain, the code to calculate the Butterworth IIR filter coefficients is called.

These coefficients are calculated for a direct form II filter algorithm. The coefficients for the filters are floats, which allow the system to create filters accurately throughout a 1 Hz to 120 kHz range. After the coefficients are calculated, the filter can be run. When you touch the “RUN” button, the code begins the execution of the filter.

The first thing that happens in the filter routine is that the ADC is started in a free-running mode. That means it initiates a new ADC reading, waits for the reading to complete, signals (through a register bit) that there is a new reading available, and then starts the cycle again. So, the code must monitor this register bit, and when it is set, the code must quickly get the new ADC reading and filter it, and then send that filtered value to the DAC for output.

After this, it checks for clipping in the ADC or DAC. The input to the DFS is AC-coupled. Then, when it enters the analog front-end (AFE), it is recentered at about 1.65 V. If any ADC sample gets too close to 0 or too close to 4095 (it’s a 12-bit ADC), it is flagged as clipping, and the front panel input clipping LED will light for ~ 0.5 seconds. This could happen if the input signal is too large or the input gain dial has been turned up too far.

Similarly, the DAC output is checked to see if it gets too close to 0 or to 2047 (we’ll explain why the DAC is 11 bits in a moment). If it is, it is flagged as clipping, and the output clipping LED will light for ~0.5 seconds. Clipping of the DAC could happen because the digital gain has been set too high. Note that the output signal could be set too high, using the output gain dial, and it could be clipping the signal, but this would not be detected as the amplified analog back-end (ABE) signal is not monitored in the micro.

Now to why the DAC is 11 bits. In the micro, it is actually a 12-bit DAC, but in an effort to get the sample rate as fast as possible, I discovered that the DAC had an unspec’d slew rate limit of somewhere around 1 volt/microsecond.

To work around this, I divide the signal being passed to the DAC by two so the DAC’s output voltage doesn’t have to slew so far. This is compensated for in the ABE as the actual gain of the output gain adjust is actually 2 to 10, but represented as 1 to 5. [To those of you who are questioning why I didn’t set the reference to 1.65 (instead of 3.3 V) and use the full 12 bits, the answer is this micro has a couple of issues on its analog reference system that precluded using 1.65 V.]

One last task in the filter “running” loop is to check if the “Stop” has been pressed. This a simple input bit read so it only takes few cycles.

A couple of notes on filtering: You may have noticed that there is an extra filter you can select – the “Pass-Thru”. This takes in the ADC reading, “filters” it by only multiplying the sample by the selected digital gain. It then outputs it to the DAC. I find this useful for checking the system and setup.

Another note on filtering is that you will see, in the code, that a gain offset is added when filtering. The reason for this is that, when using a high-pass or band-pass filter, the DC level is removed from the samples. We need to recenter the result at around 2048 counts. But we can’t just add 2048, as the digital gain also comes into play. You’ll see this compensation calculated using the gain and applied in the filtering routines.

Performance

I managed to get the ADC and DAC to work at 923,645 samples per second (sps) when using any of the 2-pole filters. This is a Nyquist frequency around 462 kHz. Since the selectable upper rate for a filter is 120 kHz, we get an oversample rate of almost 4. For 4-pole filters, the system runs at 795,250 sps, for an oversample rate of around 3.3.

The 4-pole filters are slower as they are created by cascading two 2-pole filters. [To check these sample rates and see if the loop has enough time to complete before the following sample is read, I toggle the D4 digital output as I pass through the loop. I then monitor this on a scope.]

The noise floor of the output signal is fairly good, but as I built this on a protoboard with no ground planes, I think it could be lower if this were built on a PCB with a good ground plane. The limiting factor on my particular board, though, is the spurious free dynamic range (SFDR).

I do get harmonic spurs at various frequencies, but I can get up to a 63 dB SFDR. This is not far from the SFDR spec of the ADC. I did notice that the amplitude of these harmonic spurs changed when I moved cables inside the enclosure, so good cable management may improve this.

Use of AI

Recently, I’ve been using AI in design, and I like to include quick information describing if AI helped in the design—here’s how it worked out. The code to initialize the ADC was quite difficult, mostly because there was a lot of misinformation about this online.

I used Microsoft Copilot and ChatGPT to assist. Both fell victim to some of the online misinformation, but by pointing out some of the errors, I got these AI systems close enough that I could complete the ADC initialization myself.

To design the battery charge indicator on the splash screen, I used the same AI. It was a pure waste of time as it produced something that didn’t look like a battery – it was easier and faster to design it myself.

The code for the filter coefficients was difficult to track down online, and ChatGPT did a much better job of searching than Google.

For circuit design, I tried to use AI for the Sallen-Key filter designs, but it was a failure, just a waste of time. Stick to the IC supplier tools for filter design.

Tried to use AI to design a nice splash screen, but I wasted more time iterating with the chatbot than it took to design the screen.

I also tried to get AI to design an enclosure with a viewable LCD, BNC connectors, etc. To be honest, I didn’t give it a lot of chances, but it couldn’t get it to stop focusing on a flat rectangular box.

Modifications

The code is actually easy to read, and you may want to modify it to add features (like a circular buffer sample delay) or modify things like the filter coefficient calculations. I think you’ll find this DFS has a number of uses in your lab/shop.

Physical AI Models- which power robots, autonomous vehicles, and other intelligent machines — must be safe, generalized for dynamic scenarios, and capable of perceiving, reasoning and operating in real time. Unlike large language models that can be trained on massive datasets from the internet, physical AI models must learn from data grounded in the real world.

However, collecting sufficient data that covers this wide variety of scenarios in the real world is incredibly difficult and, in some cases, dangerous. Physically based synthetic data generation offers a key way to address this gap.

NVIDIA recently released updates to NVIDIA Cosmos open-world foundation models (WFMs) to accelerate data generation for testing and validating physical AI models. Using NVIDIA Omniverse libraries and Cosmos, developers can generate physically based synthetic data at incredible scale.

Cosmos Predict 2.5 now unifies three separate models — Text2World, Image2World, and Video2World — into a single lightweight architecture that generates consistent, controllable multicamera video worlds from a single image, video, or prompt.

Cosmos Transfer 2.5 enables high-fidelity, spatially controlled world-to-world style transfer to amplify data variation. Developers can add new weather, lighting and terrain conditions to their simulated environments across multiple cameras. Cosmos Transfer 2.5 is 3.5x smaller than its predecessor, delivering faster performance with improved prompt alignment and physics accuracy.

These WFMs can be integrated into synthetic data pipelines running in the NVIDIA Isaac Sim open-source robotics simulation framework, built on the NVIDIA Omniverse platform, to generate photorealistic videos that reduce the simulation-to-real gap. Developers can reference a four-part pipeline for synthetic data generation:

• NVIDIA Omniverse NuRec neural reconstruction libraries for reconstructing a digital twin of a real-world environment in OpenUSD, starting with just a smartphone.
• SimReady assets to populate a digital twin with physically accurate 3D models.
• The MobilityGen workflow in Isaac Sim to generate synthetic data.
• NVIDIA Cosmos for augmenting generated data.

From Simulation to the Real World

Leading robotics and AI companies are already using these technologies to accelerate physical AI development.

Skild AI, which builds general-purpose robot brains, is using Cosmos Transfer to augment existing data with new variations for testing and validating robotics policies trained in NVIDIA Isaac Lab.

Skild AI uses Isaac Lab to create scalable simulation environments where its robots can train across embodiments and applications. By combining Isaac Lab robotics simulation capabilities with Cosmos’ synthetic data generation, Skild AI can train robot brains across diverse conditions without the time and cost constraints of real-world data collection.

Serve Robotics uses synthetic data generated from thousands of simulated scenarios in NVIDIA Isaac Sim. The synthetic data is then used in conjunction with real data to train physical AI models. The company has built one of the largest autonomous robot fleets operating in public spaces and has completed over 100,000 last-mile meal deliveries across urban areas. Serve’s robots collect 1 million miles of data monthly, including nearly 170 billion image-lidar samples, which are used in simulation to further improve robot models.

Lightwheel, a simulation-first robotics solution provider, is helping companies bridge the simulation-to-real gap with SimReady assets and large-scale synthetic datasets. With high-quality synthetic data and simulation environments built on OpenUSD, Lightwheel’s approach helps ensure robots trained in simulation perform effectively in real-world scenarios, from factory floors to homes.

Data scientist and Omniverse community member Santiago Villa is using synthetic data with Omniverse libraries and Blender software to improve mining operations by identifying large boulders that halt operations.

Undetected boulders entering crushers can cause delays of seven minutes or more per incident, costing mines up to $650,000 annually in lost production. Using Omniverse to generate thousands of automatically annotated synthetic images across varied lighting and weather conditions dramatically reduces training costs while enabling mining companies to improve boulder detection systems and avoid equipment downtime.

FS Studio partnered with a global logistics leader to improve AI-driven package detection by creating thousands of photorealistic package variations in different lighting conditions using Omniverse libraries like Replicator. The synthetic dataset dramatically improved object detection accuracy and reduced false positives, delivering measurable gains in throughput speed and system performance across the customer’s logistics network.

Robots for Humanity built a full simulation environment in Isaac Sim for an oil and gas client using Omniverse libraries to generate synthetic data, including depth, segmentation and RGB images, while collecting joint and motion data from the Unitree G1 robot through teleoperation.

Omniverse Ambassador Scott Dempsey is developing a synthetic data generation synthesizer that builds various cables from real-world manufacturer specifications, using Isaac Sim to generate synthetic data augmented with Cosmos Transfer to create photorealistic training datasets for applications that detect and handle cables.

Conclusion

As physical AI systems continue to move from controlled labs into the complexity of the real world, the need for vast, diverse, and accurate training data has never been greater. Physically based synthetic worlds—driven by open-world foundation models and high-fidelity simulation platforms like Omniverse—offer a powerful solution to this challenge. They allow developers to safely explore edge cases, scale data generation to unprecedented levels, and accelerate the validation of robots and autonomous machines destined for dynamic, unpredictable environments.

The examples from industry leaders show that this shift is already well underway. Synthetic data is strengthening robotics policies, improving perception systems, and drastically reducing the gap between simulation and real-world performance. As tools like Cosmos, Isaac Sim, and OpenUSD-driven pipelines mature, the creation of rich virtual worlds will become as essential to physical AI development as datasets and GPUs have been for digital AI.

In many ways, we are witnessing the emergence of a new engineering paradigm—one where intelligent machines learn first in virtual environments grounded in real physics, and only then step confidently into the physical world. The Omniverse is not just a place to simulate; it is becoming the training ground for the next generation of autonomous systems.

Gartner believes that by 2029, only 5% of automakers will maintain strong AI investment growth, a decline from over 95% today.

“The automotive sector is currently experiencing a period of AI euphoria, where many companies want to achieve disruptive value even before building strong AI foundations,” said Pedro Pacheco, VP Analyst at Gartner. “This euphoria will eventually turn into disappointment as these organizations are not able to achieve the ambitious goals they set for AI.”

Gartner predicts that only a handful of automotive companies will maintain ambitious AI initiatives after the next five years. Organizations with strong software foundations, tech-savvy leadership, and a consistent very long-term focus on AI will pull ahead from the rest, creating a competitive AI divide.

“Software and data are the cornerstones of AI,” said Pacheco. “Companies with advanced maturity in these areas have a natural head start. In addition, automotive companies led by execs with strong tech know-how are more likely to make AI their top priority instead of sticking to the traditional priorities of an automotive company.”

Fully-Automated Vehicle Assembly Predicted by 2030

The automotive industry is also heading for radical operational efficiency. As automakers rapidly integrate advanced robotics into their assembly lines, Gartner predicts that by 2030, at least one automaker will achieve fully automated vehicle assembly, marking a historic shift in the automotive sector.

“The race toward full automation is accelerating, with nearly half of the world’s top automakers (12 out of 25) already piloting advanced robotics in their factories,” said Marco Sandrone, VP Analyst at Gartner. “Automated vehicle assembly helps automakers reduce labor costs, improve quality, and shorten production cycle times. For consumers, this means better vehicles at potentially lower prices.”

While it may reduce the direct need for human labor in vehicle assembly, new roles in AI oversight, robotics maintenance and software development could offset losses if reskilling programs are prioritized.

Parabolic microphones offer a fascinating blend of geometry and acoustics, enabling long-distance sound capture with surprising clarity. From dish-shaped reflectors to pinpoint audio focus, this quick primer distills the essentials for engineers and curious minds exploring high-gain directional solutions.

Parabolic microphones are specialized tools designed to capture sounds that are too faint for conventional microphones, or when precise directional focus is essential. By concentrating acoustic energy from a narrow field, a well-designed parabolic microphone can isolate a single sound source amid a noisy environment. These microphones are commonly used in nature recording, sports broadcasting, surveillance, and even drone detection.

Understanding parabolic microphones

Capturing audio for sound reinforcement, broadcast television, live performances, video production, or natural ambience requires choosing the right microphone for the job. Ideally, the sound source should be positioned close to the microphone to maximize signal strength and minimize interference from ambient noise or the microphone’s own self-noise. A signal-to-noise ratio (SNR) in the range of 40–60 dB is typically desirable. For distant or low-level sound sources, microphone’s self-noise should be especially low—below 10 dBA is recommended.

In applications like sporting events, surveillance and nature sound recording, getting close to the source is often impractical. Only a well-designed parabolic microphone can deliver suitable SNR under these conditions. Keep in mind that audio signal level drops by 6 dB every time the distance to the source is doubled, and the farther you are, the more unwanted ambient sounds creep in.

Parabolic microphones address both challenges by combining a narrow polar angle with high forward gain. Much like a telephoto camera lens, a parabolic dish offers greater magnification at long distances—but with a tighter field of view.

At the central focal point of a portable parabolic dish, incoming sound waves converge with remarkable intensity. The concept of using a parabolic (semi-spherical) reflector to capture distant sounds has been around for decades, and with good reason.

Unlike conventional microphones, a parabolic reflector acts as a noiseless acoustic amplifier—boosting signal strength without adding electronic noise. Its frequency response and polar pattern are directly influenced by the size of the dish, with larger reflectors offering narrower pickup angles and extended low-frequency reach.

As shown below, the operating principle of a parabolic microphone is straightforward to visualize. Incoming sound waves reflect off the curved surface of the dish and converge at its focal point, where the microphone element captures and converts them into audio signals with enhanced directionality and gain.

Simply put, a parabolic dish collects sound energy from a broad area and concentrates it onto a single focal point, where a microphone is positioned. By focusing acoustic energy in this way, the dish acts as a mechanical amplifier, boosting signal strength without introducing electronic noise. This passive amplification enables the microphone to capture faint or distant sounds with greater clarity, making the system ideal for applications where electronic gain alone would be insufficient or too noisy.

As an aside, although the parabolic dish is designed to reflect sound waves toward its focal point, not all waves strike the microphone diaphragm at the same angle. For this reason, omnidirectional microphones are typically used; they maintain consistent sensitivity regardless of the direction of incoming sound.

This may seem counterintuitive at first: the parabolic system is highly directional, yet it employs an omnidirectional microphone. The key is that the dish provides directionality, while the mic simply needs to capture all focused energy arriving at the focal point.

Parabolic microphones: Buy or DIY?

A complete parabolic microphone system typically includes one or more microphone elements, a parabolic reflector, a mounting mechanism to position the microphone at the dish’s focal point, an optional preamplifier or headphone amplifier, and a way to handhold the assembly or mount it on a tripod.

If you are looking to acquire such a system, you have three main paths: you can purchase a fully assembled unit that includes the microphone element and, optionally, built-in amplification; you can opt for a nearly complete setup that provides the dish and mounting hardware but leaves the microphone and electronics up to you; or you can build your own from scratch, sourcing each component to suit your specific needs.

A parabolic microphone makes an excellent DIY project for several compelling reasons. The underlying principles are fascinating yet easy to grasp, and construction is not prohibitively complex. More than just a science experiment, the finished system can be genuinely useful—whether for nature recording, surveillance, or acoustic research.

Material costs are typically far lower than those of comparable commercial units, making DIY both practical and rewarding. For that reason, the next section highlights a few key design pointers to help you build your own parabolic microphone.

In addition to the all-important dish diameter, three other factors play a critical role when selecting a reflector for a parabolic microphone: the dish’s focal-length-to-diameter (f/D) ratio, the precision of its parabolic curvature, and the smoothness of its inner surface. Each of these influences how effectively the dish focuses sound and how cleanly the microphone captures it.

Oh, this is just a personal suggestion, but I strongly recommend buying a professionally molded parabolic dish rather than attempting to make one from scratch. The reflector is the most critical part of the system, and its precision directly affects performance.

A quick pick is the plastic parabolic dish from Wildtronics, which offers reliable geometry and build quality for DIY use. My purpose in writing this note is not to endorse any particular parabolic dish, but simply to offer a practical pointer that may help others construct a working parabolic microphone with minimal frustration and cost.

Once you have a reliable dish, the rest of the build becomes far more manageable. You can then add mechanical accessories such as mic mounts, handles, tripod brackets, and a suitable windshield to reduce wind noise and protect the microphone.

Vital components like an electret microphone element and supporting audio electronics—whether a simple preamplifier or a full recording interface—complete the setup. With the dish as your foundation, assembling a functional and effective parabolic microphone becomes a rewarding DIY process.

Acoustic sensor for DIY parabolic mic

To wrap up, here is a proven acoustic sensor design for a DIY parabolic microphone, built around the Primo EM272 electret condenser microphone.

In an earlier prototype, I used a slightly tweaked prewired monaural audio amplifier module to process signals from this stage, and it performed exactly as expected.

Whether you are a field recordist, audio tinkerer, or simply acoustically curious, there is more to explore.

Allegiance Group signed a Memorandum of Understanding (MoU) with Karnataka to develop an India-Taiwan Industrial Park, creating a dedicated hub for advanced electronics and semiconductor manufacturing.

Karnataka has secured a major foreign investment with Taiwan-based Allegiance Group signing an MoU to establish a ₹1,000-crore India-Taiwan Industrial Park (ITIP) focused on electronics and semiconductor manufacturing. The agreement was signed by IT/BT director Rahul Sharanappa Sankanur and Allegiance Group vice president Lawrence Chen.

Chief Minister Siddaramaiah welcomed the investment, stating that the project will bring cutting-edge technologies to the state and enhance India’s role in the global electronics value chain.

The proposed ITIP will be developed as a dedicated zone for Taiwanese companies specialising in advanced manufacturing, R&D, and innovation. According to the state government, the park is expected to generate 800 direct jobs over the next five years and will strengthen Karnataka’s position in high-value manufacturing.

This investment comes as Karnataka intensifies efforts to expand its manufacturing footprint. Just last week, American firm Praxair India announced plans to invest ₹200 crore in its operations in the state over the next three years.

The Allegiance Group, which recently committed ₹2,400 crore for similar industrial facilities in Andhra Pradesh and Telangana, said the Bengaluru project would act as a strong catalyst for Taiwanese companies entering the Indian market. “The ITIP will help Taiwanese firms scale in India and support the growth of the semiconductor and electronics ecosystem,” said Lawrence Chen.

IT/BT minister Priyank Kharge stated that the facility will deepen India-Taiwan business ties and strengthen collaboration in emerging technologies. The project aims to build a full supply chain ecosystem, including components, PCBs, and chip design, while also encouraging technology transfer and global best practices.

Industries minister M.B. Patil noted that Karnataka has signed over 115 MoUs worth ₹6.57 lakh crore in the last two years, and continues to attract leading global manufacturers such as Tata Motors, HAL, and Bosch.

The MRAM Global Innovation Forum is the industry’s premier platform for Magnetoresistive Random Access Memory (MRAM) technology, bringing together leading magnetics experts and researchers from industry and academia to share the latest MRAM advancements. Now in its 13th year, the annual one-day conference will be held the day after the IEEE International Electron Devices Meeting (IEDM) on December 11, 2025 from 8:45am to 6pm at the Hilton San Francisco Union Square Hotel’s Imperial Ballroom A/B.

The 2025 MRAM technical program includes 12 invited presentations from leading global MRAM experts, as well as an evening panel. The programs will throw light on technology development, product development, tooling and other exploratory topics.

MRAM technology, a type of non-volatile memory is known for its high speed, endurance, scalability, low power consumption and radiation hardness. Data in MRAM devices is stored by magnetic storage elements instead of an electric charge, in contrast to conventional memory technologies. MRAM technology is increasingly used in embedded memory applications for automotive microcontrollers, edge AI devices, data centers, sensors, aerospace, and in wearable devices.

“The STT-MRAM market is growing rapidly now, especially with use of embedded STT-MRAM in next-generation automotive microcontroller units,” said Kevin Garello, MRAM Forum co-chair (since 2021) and senior researcher engineer at SPINTEC. “I expect edge AI applications to be the next big market for STT-MRAM.”

“I am pleased to see that over the years, the MRAM Forum series has grown into a landmark event within the MRAM industrial ecosystem,” said Bernard Dieny, former MRAM Forum co-chair (2017–2023), and director of research at SPINTEC. “We are witnessing a steady increase in the adoption of this technology across the microelectronics industry, and the initial concerns associated with this new technology are steadily fading away.”
