Abstract
A computer-implemented method for instruction-level tracing for analyzing processor failure includes detecting a failure during operation of a processor circuit. The method further includes parsing a miscompare trace to determine a plurality of opcodes executed by the processor prior to the failure. The method further includes generating a workload comprising a set of opcodes by filtering the set of opcodes from the miscompare trace. The method further includes performing a consistency check of the workload to determine a commit ratio of the workload, the commit ratio indicative of a number of times the failure occurs when the workload is executed a predetermined number of times. The method further includes using the workload for debugging the failure based on the commit ratio being above a predetermined threshold.
