Title: System and method for converting polygon-based wires of an integrated circuit design to path-based wires

Abstract: A system and method is disclosed for converting a polygon-based wire in an integrated circuit to an object-based wire element. In one aspect of the invention, a recognition engine attempts to recognize polygonal wires in response to a wire recognition statement. First, a polygon is located and analyzed. A path having a centerline and a width is deduced from the analysis of the polygon. The path is converted into a candidate polygon that is compared with the current polygon. If the candidate polygon is substantially similar (i.e., identity is not required) to the current polygon, then the path is used to configure an object-based wire element. The geometries of the object-based wire element are then compared to corresponding geometries in a support view. If the geometries of the layers of the wire element are entirely contained within the geometries on the respective layers of the support view, then the wire element is considered recognized. The wire element is then added to a recognized view.
