Abstract

An incremental speculative merge structure which enables the elimination of invalid merge candidates without requiring the discarding of the speculative merge structure and all verification results obtained upon that structure. Targets are provided for validating the equivalence of gates g1i and g2i, and the fanout references of g1i and g2i are provided to a controllable multiplexer set to output g1i. Upon determining nonequivalence of g2i, of failing to proved equivalence, the multiplexer is switched to output the g1i fanout reference, thus undoing the incremental speculative merge.
