Abstract
Methods and systems are provided for reducing an original circuit design into a simplified circuit design by merging gates that may not be equivalent but can be demonstrated to preserve target assertability with respect to the original circuitry design. A composite netlist is created from the simplified netlist and the original netlist. The composite netlist includes a number of targets that imply the existence of a target in the simplified netlist and a corresponding target in the original netlist. The implications are verified and then validated to ensure the simplified circuit design is a suitable replacement for the original circuit design.
