Abstract
An approach is provided in which a model verification system partitions one of a design specification's circuit design properties into multiple unsolved cases. The model verification system then performs property checking on one of the unsolved cases against a corresponding circuit design model, which results in a property checked solved case and a subset of unsolved cases. In turn, the model verification system performs sequential equivalence checking on one or more of the subset of unsolved cases by checking their sequential equivalence against the property checked solved case. As a result, the model verification system stores the cases as sequentially equivalent solved cases and verifies of a portion of the design specification against a portion of the circuit design model.
