Abstract

Some embodiments of the invention provide a method of identifying a group of routes for a set of nets. The group of routes includes one route for each net in the set of nets. The method identifies a set of routes for each net. It then iteratively selects one identified route for each net. During each iteration, the method selects the identified route that least increases a tracking cost that accounts for each of the previously selected routes.
