The metrics to measure the effectiveness of Safety Mechanisms include code coverage rate, SPFM (Single- point failure metric) and LFM (Latent failure metric). Especially in SPFM and LFM, if the specified value is not reached on the Fault Injection Simulation (using Gate Level) at the end of verification, it will cause iterations, which will cause a significant increase in time and cost compared to consumer LSIs.
A method for efficiently performing a logic simulation of the Safety Mechanism will be described.
QUANTITATIVE GOALS OF LSI VERIFICATION FOR ISO 26262
In an ISO 26262 compliant LSI, it is required to achieve the quantitative target value of hardware metrics for each ASIL (Automotive Safety Integrity Level). The hardware metrics
