PaperFlux is a small connected object that once a week prints a summary of the user’s GitHub activity on thermal paper: stars, followers, commits from the last seven days, languages and main repositories. The board downloads a black-and-white PNG image generated by a server over HTTPS and sends it to a 58 mm thermal printer. The project is by Alban Petit and covers the period from October 2024 to September 2026. It is a complete example of a connected object that brings together custom electronics design, embedded firmware, a production web service and mechanical modelling.

The board measures 33.55 × 50.05 mm and has four M2 mounting holes. The total PCB thickness is 1.58 mm, with an ENIG finish. The routing counts a little over 300 segments on the front side, around thirty on the back and about a hundred vias. The heart is an Espressif ESP32-C3-MINI-1, flanked by a Diodes AP33772S controller in a WQFN-24 package with 0.5 mm pitch and I²C address 0x52.

USB-C PD power and the 3.3 V rail

The board is connected to a USB-C Power Delivery charger and negotiates a voltage of 9 V, with 5 V as fallback, which powers both the electronics and the printer. The AP33772S controller talks to the charger on the CC1 and CC2 lines, where the pull-down resistors R4 and R5 are 5.1 kΩ. It also measures current through the R6 shunt of 5 mΩ and monitors temperature via the NTC1 thermistor.

Once the voltage is established, the AP33772S closes the two MOSFETs Q1 and Q2, both DMN3009SFG. The ESP32-C3 is powered through the AP33772S switch: if a protection trips and cuts the output, the microcontroller shuts down together with the printer. The AP63203 converter produces a 3.3 V rail with current up to 2 A, using a Würth WE-MAPI 3015 inductor of 3.9 µH. The connector is a JAE DX07S016JA1R1500. A TI TPD4E02B04 also comes into play for line protection and, on the I²C bus, a TI PCA9306 level shifter.

The ESP32-C3 firmware and PNG streaming to the print head

The firmware connects to Wi-Fi, synchronises the clock via NTP and checks every minute whether it is time to print a receipt; by default the receipt is due once a week. When the time comes, the board calls the web service endpoint. The server collects the GitHub statistics, lays out an HTML template in a headless Chromium and converts the screenshot into a black-and-white PNG exactly as wide as the print head. The PNG generated by the server is 384 px wide and in 1-bit format.

The firmware decodes the PNG on the fly and sends it to the printer line by line. The DP-EH400/2 thermal printer has a print width of 384 dots and a TTL interface, with a UART connection at 9600 baud. The project uses KiCad for the schematic and layout, PlatformIO with Arduino on ESP32-C3 for the firmware, and on the server side Ruby 3.3 with Sinatra, Ferrum, ImageMagick, Kamal, Docker and GitHub Actions. Mechanical modelling is done in FreeCAD.

• Espressif ESP32-C3-MINI-1, the microcontroller with Wi-Fi
• Diodes AP33772S, the USB-C Power Delivery controller with I²C address 0x52
• 2 × DMN3009SFG, the MOSFETs that close the output
• Diodes AP63203, the converter that produces the 3.3 V rail up to 2 A
• Würth WE-MAPI 3015 of 3.9 µH, the converter inductor
• TI PCA9306, the I²C level shifter
• TI TPD4E02B04, the line protection
• JAE DX07S016JA1R1500, the USB-C connector

Anyone who wants to rebuild the project will find the full account of the work, from the KiCad schematic to the web service, on the maker’s site. The text contains precise numbers: the 33.55 × 50.05 mm board, the 5 mΩ shunt, the 384 px PNG, the UART at 9600 baud. These are all figures that matter to anyone who has to replicate the same chain, from the USB-C connector to the thermal print head.

For assembly you need a USB-C PD charger capable of negotiating 9 V, a USB-C to USB-C data cable and a thermal printer compatible with the DP-EH400/2 format. For those starting from scratch with the ESP32-C3, a mini ESP32-C3 module is the simplest starting point to try the firmware before soldering the final board.

Infineon Technologies AG is setting up Europe’s first high-volume manufacturing facility for gallium nitride (GaN) power semiconductors using 300-millimetre wafers. The company plans to invest around €1.1 billion in its existing cleanroom facilities at its Villach site in Austria by 2034, using and upgrading the current infrastructure to expand production capacity more efficiently and at a lower cost. Manufacturing is expected to begin by the end of 2027. The investment aims to meet growing demand for energy-efficient power chips used in AI data centres, energy infrastructure, electric vehicles, robotics and consumer electronics. GaN semiconductors can improve power-conversion efficiency, reduce energy losses and enable smaller, more compact electronic systems.

Infineon is a leading developer of gallium nitride (GaN) power semiconductors. Two years ago, the company achieved a major technological milestone by successfully processing GaN wafers measuring 300 millimetres in diameter. These larger wafers can produce around 2.3 times more chips per wafer than conventional 200-millimetre wafers, making manufacturing more efficient and cost-effective. Infineon is now moving this technology into high-volume production to supply customers with next-generation power semiconductors.

“This substantial investment shows our clear commitment to strengthening the European semiconductor ecosystem and Europe’s technological sovereignty. By establishing high-volume manufacturing on 300-millimeter wafers, we will be the first company in the world to bring gallium nitride power electronics into volume production,” says Jochen Hanebeck, CEO of Infineon Technologies AG. “In doing so, we are paving the way for the widespread use of gallium nitride in a wide range of key applications in areas such as artificial intelligence, energy infrastructure, e-mobility and robotics. This new, state-of-the-art manufacturing facility translates innovation leadership into direct customer benefits.”

Christian Stocker, Federal Chancellor of the Republic of Austria: “With Infineon’s billion-euro investment, we are witnessing one of the largest single investments in the history of Austria’s high-tech industry. This is not only a strong commitment to Austria as a business location but also helps ensure that the future of the semiconductor industry will not be shaped solely in Asia or the United States, but also in Austria and Europe. Villach will thus become home to a globally unique production facility for one of the key technologies that will shape the future. This will strengthen our international competitiveness and secure jobs and value creation in Austria. After all, Austria may not be a country with unlimited natural resources, but it is a country with an unlimited wealth of talent. Our cutting-edge research sets international standards, and companies such as Infineon demonstrate every day how innovation made in Austria works. These are precisely the strengths we want to build on with our industrial strategy so that, by 2035, Austria will once again rank among the world’s top ten industrial nations.”

Wolfgang Hattmannsdorfer, Austrian Federal Minister for Economic Affairs: “Chips are as important to tomorrow’s economy as oil was to yesterday’s. Europe currently accounts for only around 10 percent of global chip production. For me, the conclusion is clear: We must also manufacture this key technology in Europe. Austria is already a leader in energy-efficient chips. Relative to our population, we rank first in the EU in business R&D spending in the semiconductor sector. With our industrial strategy, we intend to build on this lead and not only research new technologies but also manufacture them on an industrial scale. This benefits the entire economy: Statistically, every job in the chip industry can provide six additional jobs across the broader economy. That is why we intend to support Infineon’s new chip production with up to 319 million euros – subject to clear funding criteria for the location. This will ensure that public funds strengthen value creation and jobs in Austria over the long term.”

The investment in this first-of-a-kind technology is being supported under the European Chips Act. The European Commission approved €319 million in state aid. The formal funding commitment by the Austrian Federal Ministry for Economic Affairs, Energy and Tourism is expected within the stipulated time limits. By approving the funding from the Federal Ministry for Economic Affairs, Energy and Tourism, the European Commission is not only enabling the expansion of manufacturing capacities in Europe but is also generating positive spillover effects in related sectors – for example, through cross-border collaboration with universities and research institutions and improved access to innovative technologies and products for start-ups and small and medium-sized enterprises.

“Competitiveness and technological sovereignty emerge where excellent research is translated into industrial value creation. This is precisely where our flagship project comes in: From Austria, we are bringing innovation into industrial application, strengthening our technological leadership and securing highly skilled jobs. Microelectronics is a key industry with enormous leverage for the economy and society. The entire Austrian semiconductor ecosystem benefits – from research organizations and universities to industrial partners. We are thus sustainably strengthening Europe’s competitiveness and strategic autonomy in microelectronics,” emphasizes Sabine Herlitschka, CEO of Infineon Technologies Austria AG.

The investment strengthens Villach’s role as a global competence center for power electronics and new semiconductor materials. Infineon Austria currently employs around 5,800 people, approximately 4,800 of them at the Villach1 site. Together with universities, research institutions, start-ups and industry partners, Infineon forms the core of an internationally recognized microelectronics ecosystem in southern Austria. The establishment of the new 300-millimeter GaN manufacturing facility will also create positive synergies with the power electronics research and development activities located in Villach.

Gallium nitride is an advanced semiconductor material that can switch and convert electricity much more efficiently. This enables smaller, more powerful and more energy-efficient electronic systems with lower energy loss and reduced heat generation. Analysts expect the market for GaN power semiconductors to grow to approximately USD 3.5 billion by 2031, representing annual growth of around 35 percent between 2025 and 2031.2

Any engineer with hands-on experience is familiar with cables which are shielded with a woven, all-metal braid, seen in Figure 1. Braided shielding has been used for decades. It is widely available, has modest cost, and it works—at least up to a point.

Figure 1 This schematic of a cable using conventional braided shielding illustrates the RF barrier it provides; the illustration shows multiple basic-wire conductors, but the same concept is used with coaxial cables and twisted-pair cabling. Source: Stecker Express

The braid serves two complementary EMI functions in most cases. It attenuates emissions of electromagnetic energy from the cable, and, at the same time, it prevents interfering energy from reaching the cable. It’s used for cables carrying DC all the way to gigahertz signals. Shielding is used with coaxial cable, twisted pairs, multiconductor cable assemblies, and more.

Engineers have a love/hate relationship with cables that use a tightly woven conductive braid for shielding. On one side, it’s an essential passive component for maintaining signal integrity, and how can you put a price on that, especially when there seems to be no viable alternative. On the other side, it adds bulk, weight, cost, and routing challenges to the end-product.

Shielded cable also has termination challenges. Every hands-on engineer can tell “horror stories” of trying to cleanly terminate the shield to the connector, especially if it’s being done by hand without the right tools or jigs. Those tiny cut shards of braid that “fall” when trimming it can easily short the cable, and nearby circuit board, and cause general troubleshooting havoc.

The shielded-cable dilemma increases in today’s world of complex cabling in small spaces, with design emphasis on cable size, weight, and performance. Cables with conventional braided shields—almost always made of copper, but sometimes other metals such as aluminum are used—are relatively heavy and bulky.

Furthermore, the relative proportion of their overall weight and bulk increases compared to core cable size as the core that is being shielded shrinks down. That creates a dilemma for designers as gigahertz cables go down to millimeter-levels diameter, and the weight and bulk of the shielding soon become a significant design issue.

There’s even another insidious concern: performance. As frequencies reach in the multi-gigahertz range, the shielding performance of the braid decreases. The tiny voids in the woven braid become “open windows” to the short-wavelength RF energy. These shielded cables also restrict movement, can be difficult to handle and install, and their “shape memory” makes routing and rerouting more difficult.

Tighter weaves improve the situation somewhat, but at a cost in materials, flex, weight, and other factors.

Some cables use a solid foil as a first-layer shield, which is then covered with a braided shield. This improves RF shielding to nearly 100%, but further increases cost and weight and adds to termination complexity.

What can be done?

New shielding technologies and approaches are needed as cable applications shift. A vendor-authored article I saw highlighted the ARACON shielding system from Micro-Coax, a division of Amphenol. It’s based on a very different approach to creating the RF cage around the signal-carrying conductors.

Instead of woven metal braid, it uses lightweight, ultrathin, and extremely strong DuPont Kevlar fibers to create a textile-like material that then is coated with either nickel or silver (for solderability). It forms a composite shielding braid that is up to 80% lighter than copper, while still providing strong EMI/RFI protection, lightning protection, and mechanical robustness.

The conducting coating adheres to the fabric-like fibers to form a “wrapper” against electromagnetic energy. The result is a thin braid-equivalent that slips onto the cable core like a thin, open-ended, super-flexible sock. It can be used with coaxial cable, twisted pair, and even wire bundles, shown in Figure 2.

Figure 2 The ARACON shielding system uses a thin but super-tough fabric sock that slips over the conductor or wire bundle to be shielded. Source: Micro-Coax

To get a sense of the bulk differences, the density of aramid fibers is only 1.44 grams per cubic centimeter (g/cc), compared to copper at 8.9 g/cc. Even with the addition of the metal coatings, the density of fibers ranges from 3 g/cc to 5 g/cc. At the same time, the tensile strength of the aramid core, at 350 kilopounds per square inch (Ksi) is 3 to 10 times higher than that of traditional or high-strength copper cores (35 Ksi to 95 Ksi).

Its other attributes are flexibility and longevity. It has been tested to withstand over 50,000 flex cycles over a 180-degree arc; installs easily, as it cuts like fabric with standard tools; and it offers corrosion resistance (important in many real-world settings). Termination techniques are similar to those for wire-braided shields.

It meets or exceeds the many stringent mil/aero and space-related electrical, mechanical, and outgassing performance standards for shielding (it’s a long list), but with far less bulk and weight. Micro-Coax says it can be braided and fabricated by wire/cable vendors using standard metal-wire equipment and it supports crimping or banding, as well as soldering (if it’s silver plated).

The high surface-to-volume ratio of ARACON fibers contributes to effective RF EMI shielding, exceeding the performance of conventional shielding, as seen in Figure 3.

Figure 3 Despite its reduced bulk and weight, the Aracon approach offers approximately 20 dB greater attenuation compared to conventional copper braid (here, industry standard AA59569). Source: Micro-Coax

There’s a lot that is attractive about this shielding approach, which is not just a lab development but has been in use for over 10 years. It has been proven “in the field” in aircraft, space vehicles, and more.

While I couldn’t get comparative pricing—and direct one-to-one comparisons are difficult—I suspect it’s more costly than conventional metal-braided shielding. But I can see where the extra cost is justified in applications where lower weight and bulk, along with performance and flexibility, are more critical priorities than cost.

It feels weird to say “we’ve been a team all these years, but things have changed” to braided shielding. Still, sometimes we must acknowledge reality and move on in a somewhat different direction to meet new design demands and constraints. Perhaps that’s what will happen with the availability of this alternative to braided shielding.

Have you ever found the realities of standard braided shielding to be inadequate for your project, or that it imposed too many burdens? Did you look for alternative cable-shielding solutions? Was your search successful?

We put on a massive Haunted Circus every year for Halloween, so I built an ESP32-based controller to manage the increasingly insane amount of games, props, and custom lighting audio that makes it all happen. It can: Use up to 4 motion sensors and other GPIO based devices. I find Ultrasonic Sensors actually work pretty darn well in a haunt. Trigger up to 4 of pretty much any typical Spirit Halloween, Home Depot, etc prop that has a step pad or try me button. Play custom audio, including a beefy amp and lineout for powered speakers Sync jaw motion with overridden of props (with an extra MOSFET hooked up) Has two higher powered and very protected 5V PWM connectors specifically to make it easy to connect programmable RGB LED strings, servos, etc. Has a wireless interface via a hub, so I can monitor everything plus adjust motion range/sensitivity, volume, and other per-prop settings. It's fun to monitor activations from my phone. Can be powered with 5.9V-12V barrel jack adapters. And has a fused pass thru VOut so you can plug in the controller and one prop through the same adapter, very common use case to spiffy up a prop with custom audio, lights, etc. All of this is programmable via ESP32-S3-WROOM-1-N16R8 Having the extra storage is key for all the audio (and there's an even bigger module, but it was out stock at the manufacturer) The fortune teller in the second photo is a great example of the controller being used to its fullest. The attendant presses a remote control button to start the sequence. This wakes her up, and she does her movements while playing custom audio synced with her jaw synced to it. Plus extra props on the table go off. Plus it sets off a relay to create a lightning effect. Plus it tells a Pi to display a number in the crystal ball via a pepper's ghost effect. I had built a much simpler controller last year, and while I love that thing, I really wanted to push myself to actually have proper power regulation (instead of a USB brick), power protection, my own built-in amp instead of DFPlayer, etc. And it needed to get done in time for Halloween, so I put my mind to figuring out how to get AI to help the process. Over two months I ended up using GPT Sol 5.6 and later GPT Astra via Codex going pretty much every step of the PCB design process: Speccing out the functionality Initial design and component selection Sourcing datasheets, footprints, and 3D files Interpreting datasheets (so many datasheets) Iterating on and validating the design Building schematics in KiCad Some help with component placement (I did most of it, in hindsight I probably didn't need to) And the craziest thing, 99.9% of this PCB was routed by GPT Astra. There was a lot involved in getting it to work well enough, particularly anything in visual layout. The general process was to have AI attempt to do the work, figure out where it's struggling and critique it, iterate, and once we had a good workflow, have AI build a skill so it can do the rest of the step on its own. This was critical to getting good results, including having schematics and routing not look like a dog's breakfast. submitted by /u/bacontreatz [link] [comments]

Inductor-inductor-capacitor (LLC) applications that don’t require a closed control loop can benefit from simple and low-cost implementations.

High-power applications that require isolation and prioritize high efficiency often use inductor-inductor-capacitor (LLC) converters in either a half- or full-bridge configuration implemented on the primary side, depending on the voltages and power levels. Synchronous rectification is often mandatory to achieve good efficiency, especially with low output voltages.

When looking for closed-loop LLC controllers, there are various options on the market, which offer features for protection and a precise ±3% regulated output. For open-loop applications that can tolerate an unregulated output of ±10%, many closed-loop controller features aren’t necessary, and it often takes some effort to disable certain functions to get an open-loop design working.

LLC controller features

The feature set for an open-loop LLC controller can be divided into mandatory and optional features. Mandatory features include soft start, enable input, over-current protection (OCP) with cycle-by-cycle current limiting (hiccup mode or latch-off), and driving the primary-side power stage. Optional features may include power-good output, over- and under-voltage lockout, and driving the synchronous rectifiers.

The Texas Instruments programmable logic device (TPLD) family can implement these features to achieve a cost-effective solution for open-loop applications. Figure 1 is a block diagram of the TPLD2001-Q1. This device includes various logic blocks, internal oscillators with a clock frequency up to 25MHz, a state machine, and analog comparators, making it a good match for the features that an open-loop LLC controller requires.

Figure 1 This block diagram shows the building blocks available in the TPLD2001-Q1. Source: Texas Instruments

Open-loop LLC implementation

Generating control signals for the power stages is a simple task. For low switching frequencies, designers can use the internal pulse-width modulation (PWM) generators, but higher frequencies require a logic-based approach. One possible implementation is a classical ring buffer built from configurable one-shot blocks, which generate two inverted signals for the primary side and add dead time. Figure 2 shows an implementation that generates the two control signals for the primary side as well as two control signals for driving the synchronous rectifiers on the secondary side, with adjustable dead bands between primary and secondary.

Figure 2 This example implementation generates four output signals with an adjustable dead band, all within a single TPLD2001-Q1. Source: Texas Instruments

In this way, there is no need for a specialized synchronous rectifier controller. To enable synchronous rectification, a comparator channel can measure the primary-side current to enable synchronous rectification as soon as the converter input current rises above a decision threshold.

Figure 3 shows a design example using synchronous rectification without a specialized controller. The use of LMG2104-Q1 integrated half bridges simplifies the TPLD implementation, since these devices take care of the required dead time for the primary side by themselves.

Figure 3 This overview of an example design uses TI’s TPLD2001-Q1 as a controller. Source: Texas Instruments

It is possible to achieve OCP using the internal comparators, which disable switching if the primary-side current gets too large. The amount of available logic gates enables an implementation that does cycle-by-cycle current limiting by skipping cycles if the primary-side current reaches a set limit (Figure 4). After a certain period of time, the control logic then enters hiccup mode or latch-off, which either one-shots or one of the TPLD’s counters can easily implement. Also, during soft start, the disabled synchronous rectification ensures that no unwanted current flows from the output back to the input of the converter.

Figure 4 This example current-limit implementation also fits within the TPLD2001-Q1. Source: Texas Instruments

An enable input completes the connectivity requirements and resets the device so that it goes through soft start when enabled. For devices with several analog inputs, it is easy to add under-voltage lockout and over-temperature protection features.

Of course, there are some limitations to these programmable logic devices, although many are easy to overcome. When using the internal PWM generators, the maximum frequency is limited to <100 kHz because of the fixed-period counter value.

Because the open-loop LLC topology requires no duty cycle or frequency variation, you can build your own control signal generator using the available logic cells within the TPLD2001-Q1 to achieve your desired output frequency. A 25 MHz clock frequency is high enough to generate suitable dead times and output signal frequencies up to about 500 kHz. Higher frequencies are possible; however, the dead time becomes an increasing percentage of the total switching cycle, thereby lowering efficiency.

When using synchronous rectifier controllers and integrated power stages – which take care of the dead time by themselves – this efficiency penalty is no longer an issue. Figure 5 shows the switching waveform of the design example, using a TPLD for controlling the primary side and synchronous rectification.

Figure 5 This graph from the design example shows the switch node and current waveform. Source: Texas Instruments

If you don’t need more than two analog inputs, a smaller device such as the TPLD1202-Q1 is an option. But since that device has only one comparator, the inputs are multiplexed and therefore too slow for OCP. The discrete analog comparators available within the TPLD2001-Q1 are fast enough to implement OCP and can be used for other features like the previously described simple synchronous rectification control. If OCP is the only analog feature that you require, the smaller TPLD1202-Q1 device variant may be a good fit for more cost-sensitive applications.

Conclusion

The TPLD family offers enough flexibility to implement relatively complex control mechanisms for power converters. LLC applications that don’t require a closed control loop can benefit from a simple and low-cost implementation. Although this power tip is based on a working solution, depending on the overall requirements (for example, bidirectional operation or higher switching frequencies), some device limitations could demand a different approach. Here, the TI MSPM0 microcontroller could become a valid option.

Cadence has introduced its Maestro AI Model Portfolio to support its AI Super Agents in semiconductor and system design. The portfolio combines specialised AI models with reinforcement learning and Cadence’s existing electronic design automation (EDA) and system design automation (SDA) tools. This integrated platform aims to improve design quality, speed up engineering workflows, reduce development time and continuously improve performance based on feedback from previous tasks.

Cadence Maestro provides a secure AI platform that helps engineers handle complex chip and system design tasks. It combines specialised AI models of different sizes with trained decision-making systems and AI skills that improve through repeated use and feedback. The platform works with Cadence’s AI Super Agents, including AuraStack, ChipStack, InnoStack and ViraStack, along with its existing electronic design automation (EDA) and system design automation (SDA) tools. It can also combine Cadence’s specialised models with other advanced and open-weight AI models. Customers can deploy these capabilities through cloud services or on-premises systems, giving them greater flexibility and control over their engineering data and design workflows.

“Revolutionizing complex engineering tasks requires deep domain-specialized intelligence,” said Anirudh Devgan, president and CEO at Cadence. “Combining our Maestro portfolio of domain-specialized models with leading frontier and open-weight models enables our AI Super Agents to drive Cadence EDA and SDA tools with exceptional skill and efficiency to transform chip and system design.”

“Agentic chip design requires AI that can generate design content, evaluate tradeoffs and learn from verified engineering results,” said Tim Costa, vice president and general manager of industrial and computational engineering at NVIDIA. “Our collaboration with Cadence brings NVIDIA Nemotron, OpenShell and deep engineering expertise to Maestro’s domain-specialized models. By grounding reinforcement learning in feedback from EDA tools and deterministic solvers, we can teach agents to make better design decisions based on how well their work meets engineering objectives and constraints.”

“We are deploying Cadence’s InnoStack AI Super Agent into our production design environment,” said Hisato Yoshida, COO of Socionext. “By combining agentic AI with advanced EDA tools for physical design, we expect up to 5X overall productivity gains while maintaining design quality. We see the Maestro portfolio as the next step in driving even greater efficiency across our design process.”

“Ultra-low power devices require innovation across disciplines. Agentic AI unlocks new power opportunities,” said Garima Sharda, vice president of engineering at Silicon Labs. “By leveraging the Cadence Verisium Debug as part of ChipStack AI Super Agent, our engineering teams have achieved acceleration in root-cause analysis and end-to-end debug during pre-silicon low power verification. We look forward to realizing further benefits through Cadence’s Maestro domain-specialized models.”

A Self-Improving Learning Environment for Engineering AI

Initial results show up to 30% improvement in quality of results and up to 5X greater token efficiency versus general purpose foundation models. These gains come from a vertically integrated learning environment combining Cadence domain knowledge, curated engineering datasets, AI Super Agents, EDA and SDA tools, and evaluation harnesses. Cadence’s principled algorithms and deterministic solvers evaluate outputs against engineering objectives, constraints and ground truth, creating closed and verified feedback loops for reinforcement learning and recursive improvement.

Domain Intelligence with Intelligent Model Choice

The Cadence learning environment unifies complementary AI capabilities in a single workflow. Frontier and open-weight models provide broad language, reasoning and multimodal capabilities; the Maestro AI Model Portfolio provides domain expertise for complex chip and system design. Given a high-level objective, Cadence AI Super Agents interpret design intent, decompose tasks, orchestrate the Maestro portfolio with other leading frontier and open-weight models, and drive Cadence EDA and SDA tools. The combined solution interprets specifications, generates design content, analyzes results, evaluates tradeoffs and guides decisions based on engineering requirements, cost and security. The Maestro portfolio, including NVIDIA Nemotron and other models, can be further post-trained on a customer’s proprietary data, designs, and workflows and, by balancing EDA and SDA tool calls with LLM invocations, it significantly reduces token usage while maintaining execution efficiency.

The complete Cadence agentic environment—including AI Super Agents, Maestro AI Model Portfolio and EDA tools—can run on Cadence’s secure cloud platform, secure public clouds, or in a customer-controlled on-premises environment to meet data privacy, security and deployment requirements. Cadence and NVIDIA are also working together on agent security through integration with the NVIDIA OpenShell Reference Architecture.

Inside the architecture, platforms and security controls help enterprises coordinate AI agents, automate complex workflows, and move autonomous AI from experimentation into production.

The Importance of Orchestration: Issues Beyond Individual AI Agents

AI (Artificial Intelligence) will advance from a chatbot answering queries to one that can plan how to execute tasks, perform the jobs that software tools do, discover information, and run multi-stage workflows. The AI agents are capable of doing useful things with some oversight. But in a business workflow running across multiple systems, a specialised task or an approval stage requires more than a single agent.

Enter AI agent orchestration. Orchestration is how you ‘align the agents, the model, your tools, data sources, and workflows’ so they accomplish your objective. Orchestration gives your system the ability to pass, control dependencies, maintain context, recover from failure and know when to call a human. That’s because building an agent makes it do the task; orchestrating it makes it part of a trusted end-to-end business process.

Inside the Architecture: How AI Agent Orchestration Works

Most orchestration systems consist of multiple interacting parts. The orchestrator “knows the objective, formulates or takes a sequence of steps, delegates work, and tracks results.” One or more agents execute the specific tasks in fields like research, data extraction, processing, document generation, or software operation.

It consists of a model layer for reasoning and language generation, a memory layer for storing relevant context, and a tools layer for enabling agents to interact with business applications and external systems. Monitoring and policy controls can keep actions within boundaries.

The flow could be a straightforward linear series of steps where one agent’s final result drives the next, or more flexible with the orchestrator determining the next steps based on intermediate results. Intelligent automation could retry a step if the output is validated, or bring in a human to take over if uncertain or risky.

The description Google Cloud gave of its Gemini agent shows this shift in focus. Here’s how Thomas Kurian, President and CEO, Google Cloud, explained, “You give it objectives, not instructions. You delegate an outcome and come back to finished work.”

This principle is key to orchestrating agents: instead of explicitly ordering all actions, people can ask an agent to do a task by defining an objective, and the agent will prepare the work, choose its tools, and organise the necessary actions to achieve it. Full autonomy remains a matter of available tech and permissions.

The Framework Race: Platforms Powering Enterprise AI Agents

When it comes to libraries, frameworks offer developers reusable parts to help construct and coordinate agents. These include support for defining workflows, tool calling, state management, agent communications, and integrations with external services.

LandGraph supports stateful, graph-based workflows. They can control the flow of execution and structure more complex workflows. The goal of the OpenAI Agents SDK is to enable developers to access the primitives necessary for high-level agent commands, tools, handoffs, and guardrails. The ADK from Google supports creation and orchestration of agents, while CrewAI abstracts the orchestration of agents and tasks into collaborative workflows. Llamalndex workflows, developers can create multi-step, event-driven applications that are event driven that have data and retrieve.

However, these two options are not necessarily always exactly the same. It may be a hard decision to make because it really depends on how you work and observe the setting where you will use it. Comparing the solutions for real workloads is the key. A framework does not also mean an enterprise is fully governed. There may also be a need for additional platform services or custom development for identity management, access control, audit logging, monitoring, and approval processes.

From Context to Continuity: How AI Agent Memory Works

Memory allows an agent to utilise information other than the provided prompt. An agent with no memory would need to be prompted to recall the same information each time or may forget key details along the way.

Short-term or working memory keeps information available during the current task. Long-term memory stores information for use over a series of sessions. Semantic memory encodes information (Facts and concepts); episodic memory documents relevant episodes or events. Some systems may additionally require storing reusable procedures/skills in procedural memory.

Memory must be carefully controlled. Too little information can reduce consistency, and excess will either make the system costlier, give the user information they do not require, or in some instances, reveal confidential information. Businesses need to have a policy in place regarding what is stored, for how long, and who accesses it and when.

Memory also should not be mistaken for model training. An agent can make use of its memory at runtime without modifying the existing model parameters. The right orchestration of memory, retrieval, permission, and context selection enables an agent to provide the right information for every task.

Connecting AI to the Real World: Tools, APIs and MCP

An agent becomes more valuable when enabled to integrate with systems outside its language model. Tools and APIs allow your agents to view records, perform database searches, update tickets, produce reports, and perform supported business actions.

Model Context Protocol (MCP) is an open protocol for describing how an AI app connects to external tools and context providers. MCP servers can expose tools, resources, and other functionality to MCP clients, helping users discover and reuse those integrations in an orchestration fashion.

Connectivity isn’t the same as authorisation. Just because you’ve given an agent the access it requires to do its job, it shouldn’t be making further decision-altering production data changes, approving payments, or sharing sensitive information-which will need further verification or human approval.

Additionally, organisations need to monitor the tools’ production, test inputs, trap bugs, and secure secrets. A successful API call does not mean that you made the right call or that the response is valid.

Single Agent or Multi-Agent System? Choosing the Right Approach

A single agent architecture is often appropriate when a task has a specific goal, few interdependencies, and a simple ordering of actions. It is typically more straightforward to test, monitor, and service.

A multi-agent system might be appropriate if the work is most naturally divided among specialists. For instance, a research agent might collect data, an analysis agent might examine the data, and a reporting agent might compile the final document. The orchestrator manages the handoffs and verifies if the combined result satisfied the criteria.

Though, the introduction of agents towards the system costs us some communication overhead, more model calls, inconsistencies, more difficult failure handling, and harder-to-debug systems. A multi-agent system could become costlier and more complicated to work with than a simpler system.

The moral of the story is not to over-architect. For most projects, start with the least complicated architecture that will do the work. Use specialised agents only where they provide a measurable increase in accuracy, scale, or performance.

Keeping Autonomous AI Under Control: Governance, Security and Observability

Enterprise orchestration should, therefore, not just accomplish a task. It should be used to decide who should do what, and on which resources. Ensure all tasks that should be done are done, that what should have been done is present, what was done, and how to verify or undo what was done.

Add: Least privilege permissions, runtime enforcement of policy, protected runtime environment audit and monitoring, and human approval gates. Observability might be even more important, as the failure can happen in different agents, tools, and systems rather than in a single model response.

ServiceNow announced with NVIDIA in October this year, identifying this as a problem. Jon Sigler, Executive Vice President and General Manager of AI Platform at ServiceNow, explained, “As AI agents take on more autonomous tasks, governance and security have to extend to everything they touch.”

ServiceNow Arc is generally available under the governance of the ServiceNow Super Intelligence Control Tower and the enforcement of the NVIDIA Open Shell. Further, it discusses the intended future integration of AI Passport with NVIDIA Open Shell and NVIDIA Blue Field enforcement layers. These supposed future features should not be described as generally available.

Airing similar views, Justin Boitano, Vice President of Enterprise at NVIDIA, said, “Enterprises are using AI agents to do real work, and that means policy has to be enforced everywhere an agent runs.”

Boitano’s point is that governance must live in the execution environment where the agents operate, not in some high level policy or, worse, an application-level configuration setting. Runtime enforcement can limit an agent’s access to systems and tools, even while it carries out its multi-step work.

From Experiments to Enterprise Deployment: The Challenges Ahead

When an orchestrator makes the leap from demo to production, it will need testing. This is because single agents might get inconsistent results, misinterpret directions, pick the wrong tool, or just fail if the service, they’re attached to is unavailable. Multi-agent systems magnify these problems when one agent passes on an invalid output.

Organisations should measure the rate of task completion, quality of output, latency, cost of operation, tool-call accuracy, and policy adherence. They should additionally check failure recovery, access limits, and the ability to withstand malicious instructions included in external content.

Cost management is also an issue. A workflow that fires off many large models, transmits too much context, or offloads too many subtask requests can rack up high costs. Model routing, caching, bounded retries, and well-defined stopping conditions can all improve things.

Begin by deploying use cases, defined success metrics, and permissions within your controls. As this technology matures and grows more reliable, however, an agent’s capabilities can increase while remaining under suitable human supervision.

What Comes Next? The Future of AI Agent Orchestration

AI agent orchestration is moving into more persistent agents, reusable skills, enhanced memory, standardised integrations, and tighter runtime controls. On the enterprise side, agent discovery, centralised monitoring, and policy enforcement are also becoming key focus areas.

The real goal is not to keep adding more agents, but to make the agents coordinate reliably across processes, and in a manner that is intelligent, auditable, and limited.

Business-wise, bringing that orchestration to bear will mean balancing the degree of system autonomy with the degree of system control. An information system equipped with a certain amount of autonomy and system control. An information system that combines smart planning, serviceable memory, strong tools, measurable delivery, and deployable controls is more likely to clear the pilot hurdles and create value.

Since July the cost of my electronics hobby just jumped 80% because of the new EU import tax that takes 3€ flat per category. Now imagine buying a dozen components and a MCU from aliexpress or LCSC. Little itsy bitsy components worth pennies now get practically 300% tax. But then how else am I going to find some random buck IC. And to hell with Mouser's 30€ shipping fee. Seems like the gov finally killed the hobby for me. submitted by /u/Embarrassed_Farm_174 [link] [comments]

Just a heads-up: be careful with the IP5328P board! I built a power bank using this board and 4 × 18650 Li-ion cells (3,500 mAh each). It worked perfectly for over two years. Suddenly, the IC failed and got extremely hot. Unfortunately, I hadn't installed a fuse between the board and the cells. 🤦🏼‍♂️ All four cells ended up at just 30 mV each.
