Abstract

Some embodiments relate to a method and apparatus for performing logic equivalence checking (EC) of circuits using adaptive learning based on a persistent cache containing information on sub-problems solved from previous equivalency checking runs. These sub-problems can include basic EC tasks such as logic cone comparison and/or state element mapping.
