📄 原文摘要

advanced integrated circuits for automotive applications have become stricter than at any other time. ISO26262 (Road Vehicle Functional Safety Standard) determines the risk level associated with systematic and random failures and defines the level of risk reduction required to achieve safety levels for target applications by the automotive safety integrity level (ASIL). ISO26262 has a metric for a system’s ability to detect failures, diagnostic coverage (DC) and the requirement for ASIL is 90%, 97%, and 99% for grade B, C and D, respectively, for the single point fault metric (SPFM). Whereas several papers have been published to satisfy the high ASIL grade at SoC level, only a few works were reported at the IP level [1-3]. A paper was published for clock IP with various built-in
