Siemens software for digital industries and climate technology company to sustain designed a way to add carbon emissions data to Siemens Xcelerator. Siemens created Teamcenter Carbon Footprint Calculator software to help teams measure, simulate, reduce and track their product’s carbon footprint early in the development phase. The calculator uses sustamize’s Product Footprint Engine, which has a prepackaged CO2 Emission Factor Library “Our partnership with sustamize will enable customers to understand the environmental impact of their products and processes early in product development based on comprehensive and up-to-date data,” said Eryn Devola, Vice President of Sustainability, Siemens Digital Industries Software.

Ansis provided a commercial finite element analysis (FEA) solver capable of accelerating structural mechanical models, for example for the automotive industry. The FEA supports AMD Instinct accelerators, new GPUs for data centers and supercomputers. Ansys claims to have developed APDL code that interfaces with AMD ROCm libraries on Linux, which will support performance and scaling on AMD accelerators.

Infineon Technologies has signed a multi-year supply agreement with its headquarters in the United States II-VI Incorporated to expand the semiconductor company’s supplier base for silicon carbide (SiC) wafers. SiC, a compound of silicon and carbon, is used in industrial applications but is increasingly found in electric mobility as well. SiC power semiconductors are used in main inverters in electric vehicle transmissions, on-board battery charging units and charging infrastructures. II-VI and Infineon are also working on switching to 200mm diameter SiC wafers.

Researchers at the United StatesDepartment of Energy‘S Oak Ridge National Laboratory (ORNL) and the University of Tennessee, Knoxville, discovered a key material for fast charging lithium-ion batteries in his quest for a vehicle charge of 15 minutes or less. The material, a new molybdenum-tungsten-niobate compound, or MWNO, could replace the graphite anodes used today. “Due to this slow moving lithium ion, graphite anodes are seen as an obstacle to extremely fast charging. We are looking for new, low-cost materials that can outperform graphite, “ORNL researcher Runming Tao said in a press release.” Our approach focuses on non-graphite materials, but even these have limitations. promising, niobium-based oxides have complicated synthesis methods that are not suitable for industry. “

Qualcomm says its pipeline for winning automotive design: an estimate of the future size of the programs of the award-winning automakers from the forecasts of the automakers and tier 1 suppliers, reached $ 30 billion as of September 22, 2022. The company has attributed much of the increase to its Snapdragon Digital Chassis solutions.

the NHTSA estimates in an early version of the 2022 traffic data that 20,175 people died in road accidents in United States so far this year, up 0.5% from the first half of 2021. The full death toll for 2021 in the United States was 42,915, up 10.5% from 2020.

the United States National Highway Traffic Safety Administration (NHTSA) ordered Tesla to remember some Tesla models where the power windows do not detect obstructions when closing. Windows are a danger to anyone with a limb on the street. Tesla plans to perform an over-the-air (OTA) update to resolve the issue.

Pervasive computing

RISC-V processor intellectual property company Codasip is now a member of the OpenHW Groupwhere Codasip will contribute to the standards for RISC-V formal verification.

Flexible logic will use Semifore, Inc.CSRCompiler software on Flex Logix’s advanced inference chip design. Flex Logix manufactures eFPGAs and AI inference chips and modules. Its InferX X1 is an AI edge inference accelerator capable of handling high-volume applications. “These designs are extremely complex and the hardware and software interfaces are critical to core performance and functionality. Semifore’s CSRCompiler ensures that hardware and software interfaces work as intended and that both hardware and software teams can test the interaction during chip development, “said Charlie Roth, vice president of hardware research and development, Flex Logix, in a press release.

AMD presented the new range of Ryzen 7020 Series and Athlon 7020 Series processors for mobile phones.

Infineon introduced a single-stage flyback AC-DC controller IC for battery charging. The ICC80QSG single-stage PWM controller is used in flyback topologies in conjunction with Infineon’s CoolMOS P7 Superjunction (SJ) MOSFET devices. The advantage that designers can realize can be battery chargers with scalable power up to 130W suitable for adapters, printers, PCs, TVs, monitors, set-top boxes and audio amplifiers.


risk released its version 2022.2 of the True Code software tool, which helps software developers find and fix security vulnerabilities in embedded code. One of the updates expands error injection attack simulations into True Code. Development teams can create test cases that can be run automatically during the daily build process without the need for the physical hardware for which the software was developed. to find early development error injection vulnerabilities.
