Abstract
A method for performing equivalency checking between circuit designs is provided. The method includes partitioning the circuit designs into logic cones. The method includes comparing corresponding logic cones for equivalency. The comparing includes identifying constant registers feeding nonequivalent logic cones, and propagating a constant value associated with the constant register. The method includes repeating the comparing with the propagated constant values inserted in one of the corresponding logic cones. The method also includes detecting duplicate registers feeding nonequivalent logic cones in embodiments where no constant registers feeding nonequivalent logic cones are found.
