Abstract.A new approach for the automatic equivalence checking of behavioral or structural descriptions of designs with complex control is presented. The verification tool combines symbolic simulation with a hierarchy of equivalence checking methods, including decision-diagram based techniques, with increasing accuracy in order to optimize overall verification time without giving false negatives. The equivalence checker is able to cope with different numbers of control steps and different implementational details in the two descriptions to be compared.
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.
