Abstract
Some embodiments of the invention provide a method of routing. The method selects a net with a set of routable elements in a multi-layer layout region. In some embodiments, the method identifies a route for the net based on different congestion goals on different layers. In other embodiments, the method identifies a route for the net based on different congestion goals between different layer pairs. In some embodiments, the method identifies a route for the net based on both the different congestion goals on different layers and between different layer pairs.
