Taking Self-Driving Safety Standards Beyond ISO 26262


I participated in a couple of sessions at Arm TechCon this year, the first on how safety is evolving for platform-based architectures with a mix of safety-aware IP and the second on lessons learned in safety and particularly how the industry and standards are adapting to the larger challenges in self-driving, which obviously extend beyond the pure functional safety intent of ISO 26262. Here I w... » read more

Functional Safety Verification For AV SoC Designs Accelerated With Advanced Tools


Autonomous vehicles (AVs) will be the culmination of dozens of highly complex systems, incorporating state-of-the-art technologies in electronics hardware, sensors, software, and more. Conceiving and designing these systems is certain to be one of the greatest challenges for today’s engineers. The only greater challenge will be convincing a wary public that these automated systems are safer d... » read more

Ensuring Functional Safety For Self-Driving Cars


There may be no hotter topic in electronics than chips for autonomous vehicles. Self-driving cars have captured the public imagination and become a major area of investment. Both established automotive manufacturers and well-funded startups are producing vehicles with the highly complex chips needed to negotiate roads, deal with unpredictable humans and communicate with the cloud for machine le... » read more

Getting To Orbit And The Rocket Equation


The Apollo 12 mission recently celebrated its 50th anniversary. Launching on November 14, 1969 and returning on November 24, it put humans on the Moon for the second time. I wrote about Apollo 11 (mostly about its guidance computer) earlier in the year in my post The First Computer on the Moon. Today's post is about the rocket equation, and how challenging it is to get into orbit around th... » read more

Understanding Side Channel Attacks


Side channel attacks (SCAs) differ considerably from conventional cryptographic attacks. Essentially, side channel attacks – which can be very low-cost and non-invasive – exploit data gathered from side channels. A side channel can be exploited by simply placing an antenna, magnetic probe, or other sensor near a device or system. This allows an attacker to measure power consumption, voltage... » read more

Safety Islands In Safety-Critical Hardware


Safety and security have certain aspects in common so it shouldn’t be surprising that some ideas evolving in one domain find echoes in the other. In hardware design, a significant trend has been to push security-critical functions into a hardware root-of-trust (HRoT) core, following a philosophy of putting all (or most) of those functions in one basket and watching that basket very carefully.... » read more

Traceability Of Functional Safety Requirements In Automotive IP And SoCs


By Shivakumar Chonnad, Vladimir Litovtchenko, and Rohit Bhardwaj Developing functional safety systems, including all the components such as the system-on-chip (SoC) and IP, hinges on the ability to meet the stringent automotive functional safety requirements such as definition, implementation, verification, and validation. Depending on the Automotive Safety Integrity Level (ASIL), the functi... » read more

How Does A Changing Automotive Ecosystem Affect Tier-1 Suppliers?


Tier-1 automotive suppliers have an enormous opportunity in the development of autonomous vehicles (AVs). Fortune.com sees these vehicles contributing $7 trillion in economic activity by the year 2050. But this opportunity comes with a challenge: the whole supply chain is being disrupted by new participants and new technologies that are making these AVs possible. Semiconductor companies and spe... » read more

Modeling AI Inference Performance


The metric in AI Inference that matters to customers is either throughput/$ for their model and/or throughput/watts for their model. One might assume throughput will correlate with TOPS, but you’d be wrong. Examine the table below: The Nvidia Tesla T4 gets 7.4 inferences/TOP, Xavier AGX 15 and InferX 1 34.5. And InferX X1 does it with 1/10th to 1/20th of the DRAM bandwidth of the ... » read more

Technological Dead Ends


Sometimes something comes along that looks like it is a portent of things to come, but then turns out to be a technological dead end. For example, in the 1990s, it seemed that you couldn't go to the mailbox or rent a video without getting an AOL CD offering a free trial. They were even in some cereal boxes. It was the era of the 56Kb dialup modem, and AOL's walled garden was king as everyone we... » read more
