Zusammenfassung:Embodiments of the present invention provides methods, computer program products, and a system for processing hierarchical references for a formal equivalence check. In certain embodiments, hierarchical references of a first design are identified as functionally equivalent to hierarchical references of a second design. Value outputs of the first design can be compared to the value outputs of the second design to determine whether the value outputs of the respective designs match.
