Abstract
Some embodiments of the invention provide a method for generating a route for a net in an integrated circuit (“IC”) layout. The method receives a previously defined route. From the received route, it generates several constraining points for specifying a geometric route that is based on a particular wiring model. The method then uses the constraining points to generate a geometric route that traverses diagonal and Manhattan directions.
