The transistor level net list in turn is generated from a layout polygon database using techniques in the art. The process comprises processing the transistor level net list in the memory to define groups of transistors according to whether or not transistors in the transistor level net list are connected to a supply voltage, whether or not transistors in the transistor level net list are connected to a reference voltage and the transistor type. The groups of transistors are analyzed according to their interconnections, and their membership in groups. Finally, logic units are identified in response to the step of analyzing the groups of transistors.
