摘要
In this paper(1) we present a new graph model, called conjugate conflict continuation graph, especially to address the stacked via problem in multi-layer constrained via minimization (MCVW). An integer linear programming model (which is the first of its kind) and a simulated annealing (SA) algorithm are developed to solve MCVM The SA algorithm in average achieves 64% via reduction for the layouts obtained by a commercial tool under a very restricted situation m,here the metal wires (including pins) used in cell layouts, power rails and rings, and clock routing are treated as obstacles or fixed objects to MCVM.
