STSPIN32G4, The 1st motor controller with an integrated MCU solves 2 major challenges

Thu, 03/28/2024 - 06:58

Author: STMicroelectronics

The STSPIN32G4 integrates a three-phase gate driver, an STM32G431, and a power management system under one package to solve major engineering challenges, thus enabling new applications. While ST continues to offer STSPIN motor drivers, we also realized that engineers still face several conundrums. Designers want to run more powerful applications but must also shrink their PCBs and reduce costs. Similarly, applications demand more efficiency, but improving it by a few decimal percentage points remains a struggle. ST engineers thus launched the STSPIN32G4 because no other integrated motor controller offered such a powerful mainstream MCU and such a flexible power management system.

STSPIN32G4 and the first challenge: How to make things more powerful in a smaller design? More power under one roof The STSPIN32G4The STSPIN32G4

Let’s take the example of an engineer working on a high-end vacuum cleaner with a high-speed motor. The MCU inside the STSPIN32G4 will stand out, in this instance, because of its computational throughput. A lower-performance CPU core means a lower conversion rate when designing a field-oriented control (FOC) sensorless application. The engineer in the vacuum cleaner example would have to use two or three shunt resistors to compensate for the MCU’s lower performance. On the other hand, the greater computational throughput means a single shunt is sufficient. As a result, using the STSPIN32G4 enables the creation of a powerful application with fewer components.

More peripherals in one device

A team working on a collaborative robot or a guided vehicle would also appreciate the MCU in the STSPIN32G4 for reasons other than the bump in DMIPS. In this instance, engineers must drive two sets of wheels, but traditional motor controllers don’t have enough analog-to-digital converters to handle such a task. As a result, engineers end up using two motor drivers. The STSPIN32G4 is unique because it provides two sets of PWM timers and 12-bit ADCs, among other things. It, therefore, becomes possible to drive two motors with just one integrated device.

Saving 65% space

While it’s impossible to enumerate all the features in the STSPIN32G4, the reality is that its integrated nature is one of the best ways to solve the space challenge. Motor control applications are increasingly smaller, whether for convenience, costs, or to stand out better. Thanks to its integrated nature, the STSPIN32G4 helps reduce the overall design size by 65% compared to discrete solutions. Practically, it allows engineers to put the control system at the back of the motor and design a much smaller e-bike, vacuum cleaner, or power tool, among other things.

STSPIN32G4 and the second challenge: how to make things more energy efficient while keeping costs down? A more efficient power management

According to our benchmarks, using the new device lowers the overall power consumption by 3% to 5% compared to a system that uses external components. A saving of just a single percent already has a significant impact. ST provided such power efficiency by bringing the typical standby consumption to only 15 µA thanks to a very low-quiescent regulator. Hence, we expect engineers to create significantly more compact designs without needing an external cooling system, thus lowering the BoM.

The motor controller also supports a supply voltage of up to 75 V, compared to only 48 V previously. Additionally, the STSPIN32G4 comes with an over-current protection mechanism and a drain-source voltage (VDS) monitoring system that acts as a redundancy. It monitors the external MOSFETs and turns all gate driver outputs off if it detects an over-voltage condition. As a result, we expect engineers to use the STSPIN32G4 in appliances. Indeed, a white good connected to a grid often suffers from wide voltage variations from the mains. The greater supply voltage range and protection features of the new device will better handle these abnormal conditions.

A more flexible power management

Engineers sometimes shy away from integrated solutions, fearing they may restrict their optimization capabilities. Hence, ST ensured a high level of customization. For instance, developers can program registers through an I2C interface to use the STSPIN32G4’s VCC buck converter. Moreover, we published an application note showing how to use the buck regulator in a buck-boost configuration by adding a few external components. Finally, engineers can bypass the buck and LDO regulators to rely on only an external Vcc supply.

Teams that designed a highly precise power supply to meet the stringent requirements of their application can, thus, ignore the STSPIN32G4 regulators. In contrast, others can simplify their designs by using its VCC buck converter to power a few external components, like a memory module. Similarly, developers can choose to enable or disable the standby mode. Such a feature is vital for products like power tools. When users pick a drill after months or even years, they must use it immediately. In such a case, engineers will want to completely disconnect their system from the battery to maximize its usage.

Engineers also get a lot more flexibility in how they drive a motor. They could use a 6-step driver circuit or a field-oriented control, both with or without a sensor and with one, two, or even three shunts. It gives developers the ability to control how much measurement data they gather. Consequently, it also becomes possible to qualify an STSPIN32G4 and use it in many different applications, which can help a company shorten its time to market and optimize its operations.

How to get started The EVSPIN32G4The EVSPIN32G4

ST launched two development boards to enable teams to test and experiment with the STSPIN32G4. The EVSPIN32G4 uses STL110N10F7 power MOSFETs and a heat sink to allow an output current of up to 20 A RMS. As a result, teams can push the new devices to develop more powerful designs. However, ST is also mindful that not every designer will use the STSPIN32G4 in high-powered systems. Hence, we are also launching the EVSPIN32G4NH, a similar development board without passive cooling; NH at the end of the nomenclature stands for “no heat sink”. We also updated the X-CUBE-MCSDK to support the new boards and devices.

The EVLSPIN32G4-ACTThe EVLSPIN32G4-ACT

More recently, our teams released two reference designs. The EVLSPIN32G4-ACT drives a three-phase brushless motor supporting up to 5 ARMS and can manage a supply input of 48 V for a surprising 250 W total power in a board measuring only 62 mm x 50 mm. Additionally, it can connect to the STWIN.box (STEVAL-STWINBX1) to rapidly create a high-speed data logger. Thanks to our FP-IND-DATALOGMC software pack and Quick Start Guide, engineers have a step-by-step process to connect both boards and run applications that can gather data from the sensors on the STWIN.box and the motor itself. We even offer a GUI to help visualize the information.

The EVSPIN32G4-DUALThe EVSPIN32G4-DUAL

The other board is the EVSPIN32G4-DUAL, which combines the STSPIN32G4 and the STDRIVE101, a triple half-bridge gate driver. As a result, the board can drive two three-phase brushless motors for up to 10 ARMS output current and a supply of 74 V thanks to two power stages. Thanks to the operational amplifiers of the STSPIN32G4, it’s possible to have a sensor-less system with a single shunt current sensing or use Hall sensors and encoders with the embedded MCU. Put simply, the reference design shows how to create a powerful dual motor application in a small factor for home appliances, e-mobility, pumps, tools, and more.

Precision at all Altitudes for Aerospace: Addressing the Challenges of Additive Manufacturing in Aerospace Production.

Fri, 03/22/2024 - 13:26

The aerospace industry in India is one of the fastest growing sectors with an increasingly strong domestic manufacturing base. To gain further competitive advantage, the implementation of new technologies such as additive manufacturing has been gaining importance in the recent past. While this method leads to cost reduction of building low-volume parts, as well as enables the industry to challenge the limits of efficiency through extremely accurate and complex design executions, the quality challenges faced by this new manufacturing processes should also be thoroughly addressed. High-precision metrology solutions are not only an opportunity to optimize the manufacturing process but also offer valuable insight for material sciences and ensure the quality of the output.

Additive Manufacturing as an Opportunity in Aerospace

Air travel, a preferred mode of transportation, relies on aircraft parts meeting stringent quality standards. For instance, before a supplier commences production, up to 1500 inspection features of a turbine blade must be verified, adhering to tight tolerance ranges at every production step. Beyond this challenge, another is the vital maintenance and repair operations (MRO) which often involves replacing high-complexity, quality-intensive low-volume or single parts. Traditional manufacturing processes for MROs prove both time and cost-intensive, unable to meet the demanded complexity and accuracy efficiently. Consequently, additive manufacturing, specifically 3D printing, is increasingly integrated into the aerospace production chain in India, positioning the industry as a pioneer in additive manufacturing innovation. However, the adoption of this technology brings its own challenges, which our experience suggests can be effectively addressed through high-quality metrology solutions.

Hitting the Brake: The Process and Challenges of Additive Manufacturing

Powder is the building block of additively manufactured parts. The particles are small, typically ranging from a few micrometers to tens of microns in diameter. Their size distribution and shape influence spread ability and hence possible defects might occur during the process. The defect density is among other aspects and also a factor for recycling and aging of the powder. A uniformly distributed powder bed is the essential basis for a stable and reliable additive manufacturing process. Improper powder quality, powder rheology and the process parameters might cause voids to form in the final structure. The additive manufacturing process, unlike traditional manufacturing methods, requires powders to be melted layer by layer during the build. Melt temperatures and process parameters greatly affect the crystallography and, as a consequence, part properties. After printing, the part is still attached to the build plate. It is then heat-treated for stress relieving and removed from the build plate with a band saw or wire EDM. Some parts are then heat treated again for microstructure changes. These processes possibly influence the characteristic and accuracy of the part, impacting the quality and safety. Post which, Dimensional accuracy and surface finish are critical to ensure proper assembly and consistent matching across multiple parts. Even though additive manufacturing is an immense opportunity since it enables an unprecedented control over material microstructures. Analyzing and understanding these structures is key for an efficient and optimized process that ensures the demanded quality and safety.

Precision at all Altitudes: Overcoming the Challenges

Jet engine turbine (3D xray blue transparent)

Utilizing cutting-edge measurement and inspection equipment is crucial for meeting aerospace parts’ sophisticated requirements. Our metrology solutions support and can be implemented throughout the manufacturing process, enabling immediate corrective actions, ensuring high-quality output, and promoting sustainable resourcing. We employ Light or Electron Microscopes and CT for continuous powder characterization, identifying sources of quality issues in the powder bed during or after printing. Defective parts can be detected and fixed during the build, avoiding downstream costs and increasing yield. Optical 3D-scanners, Coordinate Measuring Machines, and high-resolution CT validate accuracy, inspect finished parts, and analyze internal structures, contributing to defining optimal settings for future processes. The comprehensive data analysis across the process chain, facilitated by metrology devices equipped with IoT and PiWeb software by ZEISS, ensures correlation and supports an efficient and optimized process. Investing in high-quality metrology and research equipment is indispensable for ensuring safety and quality in the aerospace industry, particularly as ‘Make in India’ propels the sector’s growth, with additive manufacturing playing a vital role in material science and process optimization.

 

ZEISS, as a key global provider, plays a pivotal role with its Blue Line process, contributing to the industry’s success through precise metrology and quality solutions. Moreover, the company’s commitment to excellence extends beyond mere provision, as it actively engages in collaborative ventures. The company’s globally unique application lab not only facilitates joint customer projects and scientific studies but also serves as a dynamic hub for hands-on demonstrations. This collaborative approach fosters a rich environment for learning and knowledge distribution, ensuring that the aerospace industry benefits not only from cutting-edge technology but also from shared insights and collective expertise.

In my opinion, the aerospace industry in India stands at the forefront of innovation and technological advancements, embracing additive manufacturing as a crucial element in its production chain. By leveraging cutting-edge measurement and inspection equipment throughout the entire manufacturing process, the industry can achieve immediate corrective actions, increase yield, and streamline resource utilization. With continued investments in high-quality metrology and research equipment, the aerospace sector can ensure the safety and quality of its intricate and complex components, further solidifying its position as a leader in technological innovation.

With projections indicating a doubling of air passenger numbers to 8.2 million by 2037, the advancement of all-electric and hybrid-electric propulsion for powering Advanced Air Mobility (AAM) is evolving into a billion-dollar industry. Recent assessments by Rolls Royce suggest that approximately 15,000 Electric Vertical Take-Off and Landing (eVTOL) vehicles will be indispensable across 30 major cities by 2035 solely to meet the demand for intracity travel. By 2030, top players in the passenger Advanced Air Mobility (AAM) sector could boast larger fleets and significantly more daily flights than the world’s biggest airlines. These flights, averaging just 18 minutes each, will typically carry fewer passengers (ranging from one to six, plus a pilot).

The increasing urbanization, expanding population, aging infrastructure, and the surge in e-commerce and logistics underscore the need for a contemporary, safe, and cost-effective transportation solution for both people and goods. Urban Air Mobility (UAM) presents a seamless, reliable, and swift mode of transportation, addressing present and future urban challenges. With the capacity to transform intra and inter-city transportation, UAM offers a quicker and more effective alternative to conventional ground-based transportation methods. The adoption of Urban Air Mobility hinges on five primary factors:

  • Growing demand for alternate modes of transportation in urban mobility.
  • Need for convenient, efficient and last mile delivery.
  • Zero emission and noise free mandates.
  • Advancement in technologies (Energy storage, Autonomous, Connected, Power Electronics).
  • Security.

Despite the growing Urban Air Mobility (UAM) sector, it faces significant challenges that need addressing for future growth and success. These challenges range from developing reliable electric propulsion systems to achieving autonomous flight capabilities and establishing necessary infrastructure like vertiports and charging stations. Overcoming these hurdles is vital for unlocking UAM’s transformative potential in urban transportation.

The Intelligent Cabin Management System (ICMS), utilized in aviation and rail industries, undergoes continuous advancements fueled by emerging technologies. Enhanced facial recognition algorithms, driven by artificial intelligence (AI), significantly improve efficiencies and reliability in user authentication, behavior analysis, safety, threat detection, and object tracking. Moreover, ICMS prioritizes monitoring passengers’ vital signs onboard for health safety.

This solution ensures cabin operations with a focus on passenger safety, security, and health, suitable for various passenger cabins in aircraft and rail, and particularly ideal for UAM applications. It facilitates cabin entry by authorized crew and passengers, guides seating arrangements, enforces luggage placement regulations, ensures compliance with air travel advisories, monitors passenger behavior for preemptive intervention, identifies permitted and potentially threatening objects, flags left luggage, and detects vital health parameters for real-time monitoring and control.

AI in UAM Maintenance

AI-driven predictive maintenance involves analyzing sensor data and onboard sources to anticipate UAM maintenance needs, aiding in proactive scheduling and minimizing downtime. Similarly, AI-based inspections utilize image analysis to swiftly identify potential issues during regular checks, enhancing accuracy and reducing errors. Additionally, AI supports maintenance decision-making by analyzing various factors like repair costs and part availability, providing informed recommendations. Future advancements may see autonomous maintenance systems, powered by AI, performing routine tasks such as inspections and minor repairs, improving efficiency and safety. Furthermore, AI assists technicians in diagnostics and troubleshooting by analyzing data and historical records to pinpoint issues and suggest appropriate solutions, streamlining maintenance processes and ensuring UAM operational reliability.

Conclusion

The integration of AI into UAM maintenance offers numerous benefits that significantly enhance the efficiency, safety, and reliability of UAM operations. Through proactive maintenance enabled by AI’s predictive capabilities, maintenance teams can anticipate and address potential failures before they occur, reducing unplanned downtime and enhancing operational reliability. Furthermore, AI-supported maintenance increases aircraft availability, ensuring vehicles are consistently safe and reliable, thus contributing to higher customer satisfaction and overall operational performance.

Moreover, AI-driven maintenance optimization leads to cost reduction by accurately predicting maintenance needs and minimizing unnecessary inspections and component replacements, thereby reducing labor and material costs. Additionally, AI’s continuous monitoring of UAM vehicle conditions enhances safety by detecting anomalies or safety risks in real-time, preventing accidents and ensuring timely maintenance. Overall, the application of AI in UAM maintenance represents a transformative step towards a more efficient, safe, and reliable urban air transportation system.

Automotive PCIe: To Switch or Not to Switch?

Thu, 03/21/2024 - 13:39

The myths and false economy of direct chip-to-chip PCIe connect in ADAS and vehicle autonomy applications.

PCIe’s Rising Role in Autonomous Driving and ADAS Technology

Before pondering the question of whether or not to switch, let’s first set the scene by considering why Peripheral Component Interconnect Express (PCIe) is becoming so popular as an interconnect technology in advanced driver assistance systems (ADAS) applications—and why it will be so crucial in the realization of completely autonomous driving (AD) as the automotive industry seeks standard interfaces that deliver performance while ensuring compatibility and ease-of-use.

With its roots in the computing industry, PCIe is a point-to-point bidirectional bus for connecting high-speed components. Subject to the system architecture (PCIe’s implementation), data transfer can take place over 1, 2, 4, 8 or 16 lanes, and if more than one lane is used the bus becomes a serial/parallel hybrid.

The PCIe specification is owned and managed by the PCI Special Interest Group (PCI-SIG), an association of 900+ industry companies committed to advancing its non-proprietary peripheral technology. As demand for higher I/O performance grows, the group’s scope and ecosystem reach are both expanding, and to paraphrase words from PCI-SIG’s membership page:

Current PCIe and other related technology roadmaps account for new form factors and lower power applications. Innovation on these fronts will remain true to PCI-SIG’s legacy of delivering solutions that are backward compatible, cost-efficient, high performance, processor agnostic, and scalable.

With vehicles becoming high-performance computing platforms (HPCs—and data centers, even) on wheels, these words are exactly what vehicle OEMs developing ADAS and AD solutions want to hear. Also, every generation of PCIe results in performance improvements – from gen 1.0’s data (giga) transfer rate of 2.5GT/s and total bandwidth of 4G/s (16 lanes) to today’s gen 6.0’s 64GT/s and 128G/s (16 lanes). Note: PCIe 7.0, slated to arrive in 2025, will have a data rate of 128GT/s and a bandwidth of 512GB/s through 16 lanes.

PCIe’s performance power cannot be disputed, and it will certainly be required to support the kind of real-time processing of large volumes of data needed for AI- and ML-enabled ADAS and AD applications.

But, as ever, there is debate around implementing PCIe-based architectures, not least when it comes to whether the connections between PCIe-enabled components should be direct or switched.

Making the Connection

To provide higher levels of automation, vehicles must incorporate increasingly sophisticated combinations of electronic components including central processing units (CPUs), electronic control units (ECUs), graphics processing units (GPUs), system-on-chips (SoCs), “smart sensors” and high-capacity and high-speed storage devices (such as NVMe memory).

Of these components, the ECUs (there are many) combine across separate zones based on a common functionality. These zonal ECUs communicate with HPC platforms using Ethernet. But within those platforms, there is a need for high-bandwidth processing to achieve real-time decision making.

Accordingly, PCIe technology is being used by automotive designers in a manner very similar to the way in which a data center is designed. Connecting sensors with high-speed serial outputs to processing units is best addressed with an open standard called Automotive SerDes Alliance (ASA).

In essence, there are three pillars of automotive networking (see figure 1).

Figure 1 - Three Pillars of future of Automotive NetworkingFigure 1 – Three Pillars of future of Automotive Networking

However, some SoC vendors are saying that for PCIe you can simply connect directly between chips without a switch. Well, yes, you can… but it doesn’t scale to higher ADAS levels and it’s a false economy do so.

An HPC system without a switch exponentially increases software complexity, as each end requires its own software stack. Also, there’s the “bigger picture” benefits of switched over unswitched PCIe to consider:

  • IO Bandwidth Optimization: Packet switching reduces the SoC interconnection pin count requirement which lowers SoC power and cost.
  • Peripheral Sharing: Single peripherals, such as SSD storage or ethernet controllers, may be shared across several SoCs
  • Scalability: You can easily scale for more performance without changing the system architecture by increasing switch size, SoC count and peripheral count.
  • Serviceability: PCIe has built-in error detection and diagnostic test features which have been thoroughly proven in the high-performance compute environment over many years to significantly ease serviceability.
  • And as a result of the above points, a much better total cost of ownership (TCO) is possible.

When PCIe combines forces with Ethernet and ASA, it allows for the creation of an optimized, heterogeneous system architecture (as figure 2 illustrates with respect to an ADAS example).

Figure 2 - Heterogenous architecture for ADASFigure 2 – Heterogenous architecture for ADAS

Although the three communications technologies evolved at different times to support different needs, and have their respective pros and cons, the heterogeneous architecture makes the best of each.

As mentioned, PCIe provides point-to-point connection, meaning devices are not competing for bandwidth, which is fine if only a few devices need to connect. However, an autonomous vehicle is best realized as a set of distributed workloads, which means bandwidth needs to be shared between multiple sub-system components.

In this respect, PCIe switches provide an excellent solution as they are “transparent,” meaning that software and other devices do not need to be aware of the presence of switches in the hierarchy, and no drivers are required.

The Answer: Switch

PCIe is ideal for ADAS, AD and other HPC applications within a vehicle, but its “point-to-point” connectivity has many thinking that that’s how it should be implemented—as chip-to-chip, for example. However, integrating switching using technologies such as the Microchip Switchtec family (the world’s first automotive-qualified PCIe switches) minimizes software complexity and realizes a host of other benefits for high-performance automotive systems with multiple sub-system components that demand low latencies and high data rates.

Techniques to Identify and Correct Asymmetric Wafer Map Defects Caused by Design and Process Errors

Thu, 03/21/2024 - 13:21

JAMES KIM, Senior Semiconductor and Process Integration Engineer | Lam Research

Asymmetries in wafer map defects are usually treated as random production hardware defects. For example, asymmetric wafer defects can be caused by particles inadvertently deposited on a wafer during any number of process steps. In this article, I want to share a different mechanism that can cause wafer defects. Namely, that these defects can be structural defects that are caused by a biased deposition or etch process.

It can be difficult for a process engineer to determine the cause of downstream structural defects located at a specific wafer radius, particularly if these defects are located in varying directions or at different locations on the wafer. As a wafer structure is formed, process behavior at that location may vary from other wafer locations based upon the radial direction and specific wafer location. Slight differences in processes at different wafer locations can be exaggerated by the accumulation of other process steps as you move toward that location. In addition, process performance differences (such as variation in equipment performance) can also cause on-wafer structural variability.

In this study, structural defects will be virtually introduced on a wafer to provide an example of how structural defects can be created by differences in wafer location. We will then use our virtual process model to identify an example of a mechanism that can cause these types of asymmetric wafer map defects.

Methods Figure 1 - Techniques to Identify and Correct Asymmetric Wafer Map Defects Caused by Design and Process ErrorsFigure 1. Anisotropic liner/barrier metal
deposition on a tilted structure caused by wafer warping

A 3D process model of a specific metal stack (Cu/TaN/Ta) on a warped wafer was created using SEMulator3D virtual fabrication (Figure 1). After the 3D model was generated, electrical analysis of 49 sites on the wafer was completed.

In our model, an anisotropic barrier/liner (TaN/Ta) deposition process was used. Due to wafer tilting, there were TaN/Ta deposition differences seen across the simulated high aspect ratio metal stack. To minimize the number of variables in the model, Cu deposition was assumed to fill in an ideal manner (without voids). Forty-nine (49) corresponding 3D models were created at different locations on the wafer, to reflect differences in tilting due to wafer warping. Next, electrical simulation was completed on these 3D models to monitor metal line resistance at each location. Serpentine metal line patterns were built into the model, to help simulate the projected electrical performance on the warped wafer at different points on the same radius, and across different directions on the wafer (Figure 2).

Figure 2 - Techniques to Identify and Correct Asymmetric Wafer Map Defects Caused by Design and Process ErrorsFigure 2 – Techniques to Identify and Correct Asymmetric Wafer Map Defects Caused by Design and Process Errors

Using only incoming structure and process behavior, we can develop a behavioral process model and extend our device performance predictions and behavioral trend analysis outside of our proposed process window range. In the case of complicated processes with more than one mechanism or behavior, we can split processes into several steps and develop models for each individual process step. There will be phenomena or behavior in manufacturing that can’t be fully captured by this type of process modeling, but these models provide useful insight during process window development.

Results

Of the 49 3D models, the models on the far edge of the wafer were heavily tilted by wafer warpage. Interestingly, not all of the models at the same wafer radius exhibited the same behavior. This was due to the metal pattern design. With anisotropic deposition into high aspect ratio trenches, deposition in specific directions was blocked at certain locations in the trenches (depending upon trench depth and tilt angle). This affected both the device structure and electrical behavior at different locations on the wafer.

Since the metal lines were extending across the x-axis, there were minimal differences seen when tilting the wafer across the x-axis in our model. X-axis tilting created only a small difference in thickness of the Ta/TaN relative to the Cu. However, when the wafer was tilted in the y-axis using our model, the high aspect ratio wall blocked Ta/TaN deposition due to the deposition angle. This lowered the volume of Ta/TaN deposition relative to Cu, which decreased the metal resistance and placed the resistance outside of our design specification.

X-axis wafer tilting had little influence on the device structure. The resistance on the far edge of the x-axis did not significantly change and remained in-spec. Y-axis wafer tilting had a more significant influence on the device structure. The resistance on the far edge of the y-axis was outside of our electrical specification (Figure 3).

Figure 3 - Techniques to Identify and Correct Asymmetric Wafer Map Defects Caused by Design and Process ErrorsFigure 3 – Techniques to Identify and Correct Asymmetric Wafer Map Defects Caused by Design and Process Errors Conclusion

Even though wafer warpage occurs in a circular manner due to accumulated stress, unexpected structural failures can occur in different radial directions on the wafer due to variations in pattern design and process behavior across the wafer. From this study, we demonstrated that asymmetric structures caused by wafer warping can create top-bottom or left-right wafer performance differences, even though processes have been uniformly applied in a circular distribution across the wafer.

Process simulation can be used to better understand structural failures that can cause performance variability at different wafer locations. A better understanding of these structural failure mechanisms can help engineers improve overall wafer yield by taking corrective action (such as performing line scanning at specific wafer locations) or by adjusting specific process windows to minimize asymmetric wafer defects.

Executive Blog – Companies that Embrace Digital Transformation Have More Resilient Design and Supply Chains

Thu, 03/21/2024 - 12:59

Sailesh Chittipeddi | Executive Vice President Operations | Renesas

Digital transformation has evolved quickly from a conceptual phase to a semiconductor industry change agent. The rapid take up of AI-enhanced product development is only accelerating this transformation and is further influenced by two connected trends: The movement of Moore’s Law from transistor scaling to system-level scaling, and the relatively recent redistribution of the global electronics supply chain due to the COVID-19 pandemic.

I spoke on this subject earlier this month at the Industry Strategy Symposium 2024 in Half Moon Bay, California, where leaders from across the chip industry gather annually to share their insights on technology and trend drivers and what they could mean for our respective businesses.

Between the early 1970s and around 2005, increased chip performance was largely a function of clock frequency improvements driven by advances in lithography, transistor density, and energy efficiency. With increasing transistor counts (and die size), clock frequencies are limited by interconnect delays and not by transistor performance. To overcome this challenge, designers moved to multi-core designs to increase system performance without blowing up energy. Novel packaging techniques such as chiplets and multi-chip modules are helping further improve system performance, particularly in AI chips.

A single chip package may be comprised of multiple chiplets each housing specific functions such as high-performance logic elements, AI accelerators, high-bandwidth DDR memory, and high-speed peripherals. Very often, each of these components is sourced from a different fab, a trend that has resulted in a fragmented global supply chain. This creates its own set of challenges as die from multiple fabs must be integrated into a package or system that must then be thoroughly tested. Test failures at this stage have enormous financial consequences. These challenges, require a “shift left” mindset in product development. The shift left mentality has major ramifications for how we, as an industry, should be managing our supply chains by moving the heavy emphasis from architecture/design to final system testing and quality.

Supply chain challenges during the COVID pandemic have resulted in further decentralization of the supply chain components. To illustrate the enormity of the change underway, consider that between 2022 and December 2024 construction began on 93 wafer fabs around the world. Compare that to the global construction of automated test facilities. In 2021 alone, the industry broke ground on 484 back-end test sites, which provides a measure of how committed the chip sector is to driving resiliency across the manufacturing landscape.

The Role of AI in Semiconductor Design and Manufacture

So, where does AI come into the picture?

A key area in which AI will exert its influence is the shift from an analytic to a predictive model. Today, we wait to detect a problem and then look at past data to identify the root cause of the problem and prevent it from reoccurring. This inefficient approach adds time, cost, unpredictability, and waste to the supply chain. AI, on the other hand, allows us to examine current data to predict future outcomes.

Instead of using spreadsheets to analyze old data, we build AI models that production engineers continuously train with new data. This “new” data is no longer merely a set of numbers or measurements but includes unstructured data such as die photos, equipment noise, time series sensor data, and videos to make better predictions.

In the end, it’s about pulling actionable information from a sea of data points. In other words, data without action is mostly useless. Why am I driving this point home? Because today, 90 percent of data created by enterprises is never used. It’s dark data. And when you think about AI implementation, 46 percent of them never make it from pilot to production because the complexity of the programs is not scoped appropriately.

Despite these challenges, equipment makers are already starting to implement digital transformation techniques into their product development processes. The benefits are palpable. Research from Boston Consulting Group found that companies that have built resiliency into their supply and design chains recovered from COVID-related downturns twice as fast as companies that have yet to embrace digital transformation.

At Renesas, we acquired a company called Reality AI that generates a compact machine learning model that runs on a microcontroller or microprocessor. This provides the unique ability to quickly detect deviations from normal patterns that may cause equipment problems. It allows manufacturing facilities to schedule preventive maintenance or minimize downtime associated with sudden equipment failure.

Digital Transformation Is Future-Proofing Our Industry

Digital transformation with AI is key to business success today. As the semiconductor industry undergoes a major evolution – embracing system-level design and adapting to a changing global supply chain – digital transformation and the shift left approach are powerful tools that deliver on two fronts.

The first is a productivity increase that comes from optimized tools and design processes. The closer you are to where the failure is likely to occur, the more quickly you learn and the more quickly you can fix things.

Second, and perhaps most importantly, digital transformation solves one of the biggest problems the industry has with chip design – the availability of talent. When we reduce the time taken to design a chip, we’re making our engineers far more efficient than they would be otherwise, which is increasingly important as the semiconductor industry demographic skews older.

Network RTK vs PPP-RTK: an insight into real-world performance

Thu, 03/21/2024 - 12:43

By- Patty Felts, Product Marketing Manager, Product Center Services

Australian automation and positioning technology provider conduct static and kinematic tests

Locating people, animals, or objects on Earth with high precision requires the use of GNSS receivers and the support of network RTK correction services that account for errors caused by the atmosphere, satellite clock drift, and signal delays.

Three standard approaches to correct these errors are Real Time Kinematic (RTK), Precise Point Positioning (PPP) GNSS correction services, and a combination of the two, PPP-RTK. Beyond these, a pairing device such as a survey-grade GNSS receiver or a mass-market smart antenna is also required to enhance positioning accuracy. Combining any of these approaches with one device will optimize the positioning accuracy of the end-use application.

Many GNSS navigation applications require high accuracy. The accuracy of survey-grade GNSS receivers exceeds what mass-market smart antennas can provide. Of course, this comes at a price. Still, several high-precision GNSS navigation applications can do well with the accuracy offered by mass-market smart antennas. Examples include transportation, e-mobility, IoT use cases, and field robotics. Designers aim to equip devices with reliable, high-precision positioning at a reasonable cost.

GNSS users can verify the capabilities of setups by hitting the roads and testing them in real-world situations. Doing so enables them to understand the capabilities of these setups and differentiate them.

Aptella (formerly branded as Position Partners), an Australasian provider of automation and positioning technology solutions, had the opportunity to test the capabilities of network RTK vs PPP-RTK GNSS correction services and present the findings to their client.

We will discuss the findings, but as a first step, let us review how the RTK, PPP, and PPP-RTK approaches operate, the equipment needed, and the participants in this exercise.

Network RTK, Precise Point Positioning GNSS, and PPP-RTK

The mentioned correction approaches follow different paths. RTK GNSS correction services calculate and correct GNSS errors by comparing satellite signals from one or more reference stations. Any errors detected are then transmitted using IP-based communications, which can be reliable beyond a radius of 30 km from the nearest base station. Network RTK typically requires bi-directional communication between the GNSS receiver and the service, making the solution more challenging to scale. This approach can provide centimeter-level positioning accuracy in seconds.

Precise Point Positioning GNSS correction services operate differently. They broadcast a GNSS error model valid over large geographic regions. Because this service requires only unidirectional communication (IP-based or via satellite L-band), it’s more scalable to multiple users, unlike RTK.

PPP high-precision positioning takes between three minutes and half an hour to provide a position estimate with an accuracy of less than 10 cm. Static applications such as surveying or mapping typically use this solution, but it can be a poor fit for dynamic applications such as unmanned aerial vehicles or mobile robotics.

More recently, both approaches have been combined into what is known as PPP-RTK GNSS correction services (or State Space Representation (SSR) correction services). This combination provides the accuracy of the RTK network and its fast initialization times with the broadcast nature of Precise Point Positioning. Similar to PPP, the approach is based on a model of GNSS errors that has broad geographic validity. Once a GNSS receiver has access to these PPP-RTK correction data through one-way communication, it computes the GNSS receiver position.

Survey-grade GNSS receiver versus mass-market smart antenna

Survey-grade receivers are devices typically used for geodetic surveying and mapping applications. They are designed to provide highly accurate and precise positioning information for civil engineering, construction, GIS data, land development, mining, and environmental management.

Today’s modules can access data from multiple satellite constellations and network RTK support. These devices are typically very expensive, costing thousands of dollars each, because they are highly precise, with accuracies ranging from centimeters to millimeters.

Mass-market smart antennas are specialized receiver/antenna-integrated devices designed to receive signals from satellite constellations and GNSS correction services right out of the box. Smart antennas capture and process raw data to determine precise locations. Standalone GNSS antennas don’t have a precision rating, as this depends on the integrated GNSS receiver and correction service to which the antennas are coupled.

While mass-market smart antennas are more affordable than survey-grade GNSS receivers, there is a corresponding performance trade-off, with accuracies ranging from a few centimeters to decimeters.

The following tests used a survey-grade GNSS receiver to verify control coordinates in static mode and compare RTK versus PPP-RTK results in the kinematic mode. The GNSS smart antenna was also employed as a pairing device for these static and kinematic tests.

Participating companies

Aptella is the company that conducted the performance test and presented the results to their client. However, the participation of four other companies was crucial.

AllDayRTK operates Australia’s highest-density network of Continuously Operating Reference Stations (CORS). Its network RTK correction services were used to compare with PPP-RTK.

u-blox’s PointPerfect provided the PPP-RTK GNSS correction services used in these tests.

Both correction services were coupled with a survey GNSS receiver, Topcon HiPer VR, and a mass-market smart antenna, the Tallysman TW5790.

Testing two correction services solutions

In the Australian city of Melbourne, Aptella conducted static and kinematic tests with several objectives in mind:

  • Test RTK and PPP-RTK GNSS corrections using a mass-market GNSS device like the Tallysman TW5790.
  • Demonstrate the capabilities of the Tallysman smart antenna coupled with PPP-RTK corrections.
  • Evaluate PointPerfect PPP-RTK GNSS corrections and assess “real world” results against published specifications.
  • Determine whether these specifications meet mass-market applications and e-transport safety requirements of 30 cm @ 95%.
  • Provide insight into use cases and applications suitable for PPP-RTK corrections.
Static results  gnss antenna and survey grade receiverFigure 1: gnss antenna and survey grade receiver

These tests allowed experts to compare the accuracy of RTK and PPP-RTK GNSS correction services supported by a mass-market Tallysman smart antenna.  They were also able to verify the PPP-RTK performance specifications published by u-blox.

First, a survey-grade Topcon HiPer VR GNSS receiver was used to verify the control coordinates in static mode. Once these were obtained, the Tallysman smart antenna took its place.

The table below summarizes representative results from both methods, PPP-RTK and RTK. Horizontal (planar) accuracy is similar for both, while the vertical accuracy is less accurate with PPP-RTK than RTK.

The horizontal accuracy level of RTK and PPP-RTK is in the centimeter range. In contrast, RTK maintains a centimeter range at the vertical accuracy level, but the PPP-RTK correction errors were in the decimeter range.

GNSS augmentation

 

Horizontal error (m) Vertical error (m) Horizontal 95% (m) Vertical 95% (m)
RTK AllDayRTK 0.009 0.010 0.012 0.018
PointPerfect PPP-RTK 0.048 0.080 0.041 0.074

 

Furthermore, the accuracy of the mass market device is within published specifications to meet the 30 cm @ 95% for location (plan) even when obstructed. Still, when measuring heights, these were less accurate than 2D horizontal coordinates. Absolute horizontal location accuracy meets the mass market requirement of 30 cm @ 95%, although RTK is more accurate at a vertical level than PPP-RTK.

Kinematic results

On the streets of Melbourne, Aptella experts tested RTK and PPP-RTK corrections operating in different kinematic modes with variable speeds, such as walking under open skies and driving in different environments.

The test setup using an RTK network consisted of AllDayRTK corrections and a survey-grade GNSS receiver. On the other hand, the PPP-RTK test setup was supported by u-blox PointPerfect and the Tallysman smart antenna. The antennas for both setups were mounted on the roof of the vehicle and driven through different routes to encounter various GNSS conditions.

Walking in the open sky: This test involved a walk along the riverbank. Comparing the results, both were similar, proving that PPP-RTK is well-suited for mass-market applications.

 walking tests with rtk and ppp-rtkFigure 2: walking tests with rtk and ppp-rtk

On-road driving with varying conditions: This test consisted of driving on Melbourne roads in different conditions, including open skies and partial or total obstructions to GNSS. The route included driving under bridges and areas with multipath effects. Vegetation in the area at the start of the test prevented the smart antenna’s IMU from initializing. No IMU/dead reckoning capability was used during the drive test.

The results obtained while the vehicle moved through a long tunnel under the railroad tracks were of utmost importance. In this situation, the PPP-RTK approach reported a position even in an adverse environment. In addition, PPP-RTK reconverged shortly after RTK.

Another revealing result of this second test was that the Tallysman smart antenna didn’t seem to deviate from its path when passing under short bridges.

 rtk vs ppp-rtk under a short bridgeFigure 4: rtk vs ppp-rtk under a short bridge

Driving through an outage: The outage test took place in an extended, challenging environment for GNSS. This occurred when the car drove under the pedestrian overpass at the Melbourne Cricket Ground. The PPP-RTK solution maintained the travel trajectory and effectively tracked the route (in yellow). On the other hand, the RTK network solution reported positions off the road and on the railway tracks. In this outage condition, RTK took a long time to reconverge to a fixed solution.

Open-sky driving: The final on-road test was conducted in an open-sky environment where the two setups performed similarly. They provided lane-level accuracy and suitability for mass-market applications. However, ground truthing and further testing are required to fully evaluate the accuracy and reliability of PPP-RTK in these conditions.

 correction services comparison driving through MelbourneFigure 6: correction services comparison driving through Melbourne Final remarks

The five static and dynamic tests conducted by Aptella were instrumental in assessing the effectiveness of different setups to determine the position of stationary and moving entities.

  • From the static test, Aptella concluded that PPP-RTK, coupled with the Tallysman smart antenna, provides centimeter-level horizontal accuracy and performs similarly to RTK. However, this was not the case for vertical accuracy, with PPP-RTK at the decimeter level.
  • Regarding the kinematic tests, Aptella obtained significant results, particularly when the environment impeded communication with GNSS. Even without IMU or dead reckoning, the PPP-RTK performed well with lane-level tracking. With short outages such as railway bridges and underpasses, PPP-RTK maintained an acceptable trajectory, while RTK required a long time to reconverge after emerging from these challenging conditions.
  • Overall, Aptella has demonstrated that the PPP-RTK and GNSS smart antenna combination delivers results suitable for mass-market applications requiring centimeter-level horizontal accuracy.

As mentioned above, survey-grade devices are costly although highly accurate. A combination of survey-grade GNSS receiver and network RTK correction service is recommended in geodetic surveying use cases that require high height accuracy.

Conversely, mass-market smart antenna devices using PPP-RTK corrections are less expensive but also less accurate. Nevertheless, they are well suited for static applications that don’t require GNSS heights at survey grade.

For many high-precision navigation applications, such as transportation, e-mobility, and mobile robotics, PPP-RTK is sufficient to achieve the level of performance these end applications require. The relative affordability of smart antenna devices, combined with PPP-RTK’s ability to broadcast a single stream of corrections to all endpoints, makes it easier to scale from a few prototypes to large fleets of mobile IoT devices.
