Arteris IP's Kurt Shuler, VP of Marketing, comments on ISO 26262 and the need to add SOTIF for the unknown-unkown errors in this latest Semiconductor Engineering article:
Autonomous Vehicles Are Reshaping The Tech World
September 5th, 2019 - By Kevin Fogarty
Even before fully autonomous vehicles blanket the road there is major upheaval at all levels of the industry.
Until recently, the V-system testing of ISO 26262 has been the primary functional safety method for verification and validation. It will continue to play that role, according to Kurt Shuler, vice president of marketing at Arteris IP, but it will be supplemented by other types of testing such as SOTIF (safety of the intended functionality, ISO 21448).
“SOTIF was a little controversial,” Shuler said. “It almost didn’t get passed because of what I call the philosophical element. It is designed to find faults when things are working correctly, but it also finds errors that you don’t know about. The way it goes about that is a little different from the usual approach, but there are also standards coming from SAE and others from ISO, so there will be plenty of competition for this kind of challenge to be able to verify probabilistic systems.”
