Abstract

For decades, Automotive Electronics were based on semiconductors manufactured on mature and stable process technologies. Designs were well characterized for robustness; tight screening at the production line enforced quality; using industry-standard test methodologies such as JEDEC JESD22 and JESD47 ^[1] assured reliability. Functional Safety (FuSa) relies on monitoring software, system redundancy, and safety protocols. Today, Electric Vehicles (EV) and Autonomous Driving (ADAS) require using the most advanced semiconductor technologies. Reliability requirements exceed those commonly used for commercial applications, device screening becomes a challenge, and safety measures that take effect after an error has already occurred may be insufficient.

Recently, chiplet ^[2] based designs are driving the most advanced semiconductors for High-Performance Computing (HPC) and AI. Is chiplet-based design ready to be adopted by the Automotive industry?
