RISC-V core UVM verification

"In general, CPU core development requires many more man-hours for the verification phase than the design. This is because there are a huge number of items to be verified, such as the instruction sequences and the combination of exceptions and error occurrences. This blog introduces an example of RISC-V core UVM verification that Verification Technology USA, Inc. (Vtech) provided a startup company in the US as a service."

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”
