An optimal channel routing algorithm for a detailed two-layer channel routing is proposed. Through the inclusion of appropriate net characteristic information in the node searching function, this algorithm expands far fewer nodes than Wang's (1990) algorithm to obtain optimum solutions on all of the benchmark problems presented by T. Yoshimura and E.S. Kuh (1982). Since the two-layer model has a minimum number of vias and a minimum length of wires, the proposed algorithm is suitable for the routing of channels with mixed analog/digital signals
