A two-phase fault simulation scheme for sequential circuits is proposed. The scheme is done by first performing the true value simulation with several initial patterns and then by performing the fault simulation with the rest of patterns. With this fault simulation approach, some faults which consume much simulation time can be easily and quickly identified and dropped early. As a result, significant speedup on simulation time is obtained. Five cases of faults which cause problems in fault simulation are also discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
