ABSTRACT:
Some embodiments of the invention provide a method of routing nets in a multi-layer integrated-circuit (“IC”) layout. For a particular net, the method specifies widths for routing the particular net in different directions on the same layer. It then defines a particular route for the particular net, where the route has different widths in the different directions on the same layer.
