Automatic generation of wire tag lists for a metal stack

摘要: Mechanisms are provided for pruning a layer trait library for use in wire routing in an integrated circuit design process. The mechanisms receive a plurality of wirecodes and a metal stack definition. The mechanisms generate a verbose layer trait library based on all possible combinations of the wire codes and layers of the metal stack definition. The mecha nisms generate a pruned layer trait library by pruning the verbose layer trait library to remove redundant layer traits from the verbose layer trait library. In addition, the mecha nisms store the pruned layer trait library for performing wire routing of an integrated circuit design.
