Enhanced AEC Qualification of Groudbreaking 5nm AI Processor with Liquid Cooling for Level 4 Autonomous Driving

(30:25 + Q&A) Dr. Fen Chen, Nvidia.
The rapid adoption of artificial intelligence (AI) chips in autonomous vehicles (AV), driven by the need for complex computations, necessitates robust thermal management and stringent reliability testing. Liquid cooling has emerged as a critical technology to address the thermal challenges posed by high-performance AI processors. However, the existing AEC- Q100 qualification standard, developed for air-cooled legacy chips, falls short of addressing the unique requirements of modern AV AI processors. This paper proposes an enhanced AEC-Q100 qualification methodology tailored to a custom 5nm AI processor, highlighting the need to revise the standard to consider factors such as mission profiles, cooling mechanisms, dynamic load testing, and electromagnetic compatibility. The successful qualification of the AI processor underscores the importance of evolving industry standards to ensure the reliability and performance of next-generation high-performance processors that are pivotal for the advancement of autonomous vehicle technology.  (more)
