Growing Complexity Adds To Auto IC Safety Challenges

Building together a verification approach for safety and security in automotive chips is complex, multi-faceted, and extremely difficult.
“The only way this works is with a continuous verification methodology,” said John Hallman, product manager for trust and security at OneSpin Solutions. “You need to set up a verification suite at the chip level, and when the design changes, you adapt to the update. You also need to maintain the environment against changing security vulnerabilities, which might be a model of a fault from a vulnerability in another car. But in all cases, you need the ability to make changes.”

Numerous pressures to figure all of these interactions between security and safety, design and verification requires automotive OEMs to break down silos within their organizations. According to all accounts, OEMs have realized they must bring together teams to improve communication and co-design and verify hardware, software and the system. That is the only way to cost-effectively manage the complexity of autonomous vehicle development. The good news is this also opens up new opportunities across the automotive ecosystem to support all of that work with consulting services, tools and methodologies.
