ABSTRACT:
A technique for analyzing digital circuits to identify pin swaps is provided for circuit layout and similar tasks in which the circuit is first decomposed into regions. Logic functions of the regions are decomposed into a directed graph of the logic functions. A swap structure is created in accordance with the directed graph to facilitate identification of input equivalences.
