Effective Validation Method of Safety Mechanism Compliant with ISO 26262

“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” released in Mentor Verification Horizon July 2020
