1. A method for generating multi-layer topological routes in a region of a design layout comprising:

  • a) selecting a net having routable elements on a plurality of interconnect layers; and

    b) for the selected net, defining a topological route that connects the selected net'"'"'s routable elements, wherein the topological route includes a topological via that specifies the defined route'"'"'s traversal from one interconnect layer to another interconnect layer, wherein the topological via does not have a coordinate within the region.
