The head of Tesla’s Autopilot division — Andrej Karpathy — resigned from the company after Tesla laid off 200 people in its Autopilot division and the U.S. National Highway Transportation Safety Administration broadened its safety investigation of Tesla’s Autopilot. The NHTSA last month broadened its August 2021 investigation, which was looking at why Tesla cars on Autopilot had so many crashes into stationary vehicles that were off the main road, including emergency that had stopped on the side of the road to help motorists. The broadened investigation is now called an Engineering Analysis (EA) to “evaluate additional data sets, perform vehicle evaluations, and to explore the degree to which Autopilot and associated Tesla systems may exacerbate human factors or behavioral safety risks by undermining the effectiveness of the driver’s supervision. In doing so, NHTSA plans to continue its assessment of vehicle control authority, driver engagement technologies, and related human factors considerations,” according to the NHTSA. Just last week a 2015 Tesla plowed into the back of a trailer truck that was parked at a rest stop in Florida. The two Tesla passengers died.

NASCAR used Ansys’ tools to simulate virtual crash tests that have validated the safety of its Next Gen race car, which saved time and expense in avoiding real-life crash tests. The simulation tools were also used to create parts. Ansys’s simulation tools are also helping aerospace and defense customers improve energy efficiency and reduce emissions and noise pollution.

Tower Semiconductor and Cadence are working together to build a comprehensive automotive reference design flow for automotive and mobile IC development using Cadence’s Virtuoso Design Platform and Spectre Simulation Platform. Automotive reference flow development to provide a unified design environment for chip and package co-design and simulation. “Cadence and Tower have successfully collaborated for many years, delivering solutions for RF and silicon photonics, which help our mutual customers develop advanced offerings,” said Anirudh Devgan, president and CEO of Cadence. “The mutual work we’re doing on the automotive reference flow focuses on enabling customers to develop critical automotive ICs, leveraging an integrated workflow using an all-Cadence toolset and a Tower reference design to develop compelling products faster.”

Bosch will be investing 3 billion euros in its semiconductor business by 2026 as part of the IPCEI on Microelectronics and Communications Technology. The IPCEI, or Important Project of Common European Interest, is instrument to promotes R&D that fulfills European Union Industrial Strategy. Bosch will fund two development centers – in Reutlingen and Dresden – for more than 170 million euros. The company will also spend 250 million euros to add 3,000 square meters of clean-room space at its wafer fab in Dresden and expand its 300mm chip production in Dresden to make MEMS on 300mm wafers, starting in 2026. The Reutlingen fab has been mass-producing silicon carbide (SiC) chips since the end of 2021 but will begin making gallium nitride for electromobility applications. Bosch will work on systems-on-a-chip, such as the radar sensors a vehicle uses to perform 360-degree scans of its surroundings during automated driving.

The U.S. automotive insurance company AAA released a new study about EVs that shows 25% of Americans say they would be likely to buy an electric vehicle for their next purchase chiefly to save fuel costs. The study also found that anxiety over higher purchase price, the number of charging stations, running out charge will driving, the unsuitability for long-distance travel, battery repair costs, and not being about to install a charging station where they live.

Globally in Q1 2022, electric passenger EV shipments exceeded 1.95 million units, with passenger battery electric vehicle (BEV) shipments up 90% year over year, according to Counterpoint Technology Market Research.

Security
ETH Zürich researchers have found a vulnerability that can be exploited on Intel and AMD CPUs. COMSEC, the computer security group of the Department of Information Technology and Electrical Engineering (D-ITET) at ETH Zürich, found Retbleed (CVE-2022-29900 and CVE-2022-29901), a new arbitrary speculative code execution that exploits return instructions. COMSEC says that the software construct invented in 2018 — the retpoline — that was supposed to protect the memory against the Spectre-BTI type attack can be practical to exploit. “Retpolines work by replacing indirect jumps and calls with returns,” writes COMSEC in its blog. “As it turns out, however, Retbleed is indeed practical to exploit.” COMSEC could trigger the microarchitectural conditions on AMD and Intel CPUs that can make returns predictable like indirect branches. They also made tools that could reveal locations in the Linux kernel where the conditions are met. “We found that we can inject branch targets that reside inside the kernel address-space, even as an unprivileged user. Even though we cannot access branch targets inside the kernel address-space — branching to such a target results in a page fault — the Branch Prediction Unit will update itself upon observing a branch and assume that it was legally executed, even if it’s to a kernel address,” writes the COMSEC team.  Affected Intel CPUs are here and AMD CPUs are here. Intel and AMD issued advisories on how to mitigate the issues.

Flex Logix and Microsoft are working together on the U.S. Department of Defense (DoD)’s Rapid Assured Microelectronics Prototypes (RAMP) program to produce secure ICs. Flex Logix’s eFPGA IP has been used successfully in over a dozen successful tape-outs. “Security can mean a lot of different things. For eFPGA, it means providing a means for keeping circuitry secret by programming the eFPGA in a secure environment,” said Geoff Tate, CEO and co-founder of Flex Logix in a press release. “We’re honored to be working with Microsoft to bring Flex Logix’s eFPGA technology as part of their Advanced Commercial Capabilities project for the DoD RAMP program”

Microsoft has come to a 10-year agreement with DAC (direct air capture) company Climeworks to remove 10,000 tons of carbon from the air and deposit it in the ground in Iceland. The system removes carbon from the atmosphere by pulling air through a filter with a fan and heating the filter to 100°C. The carbon interacts with basalt rock and will solidify into a rock in a few years.  The carbon is released and pumped via water into the ground. And you thought DAC stood for the Design Automation Conference.
