HCNC: High Capacity Netlist Compare

The author describes HCNC (High Capacity Netlist Compare), a technique for netlist comparison that uses the natural hierarchy of the transistor circuit to significantly increase the capacity of traditional netlist comparison algorithms. Since the natural hierarchy of the circuit is used, HCNC does not require hierarchical information from the user. HCNC also has some desirable properties for error recovery. Results from the network comparison of several large industrial circuits shall show the viability of this algorithm.
