Abstract
Some embodiments of the invention provide a method of routing nets in a region of a design layout. The region contains a plurality of nets and has multiple interconnect layers. The method identifies routes for a set of nets in the region, where some of the routes utilize vias to traverse multiple interconnect layers. The method then moves at least one via to improve the routing.
