Claim One:
1. A method of automatically improving timing of nets of a fully routed physical design solution, the method comprising: evaluating nets of a netlist against a plurality of re-routing criteria to identify the nets that satisfy at least one of the plurality of re-routing criteria, wherein the plurality of re-routing criteria comprises a timing slack threshold, a scenicness threshold, an absolute length threshold, and an average routed segment length threshold; for each of the nets that satisfy at least one of the plurality of re-routing criteria, global re-routing the net to determine a new global route for the net; identifying those of the nets that are within the new global route or within a given distance of the new global route; detailed re-routing the net in accordance with the new global route without regard to at least one of those of the nets within the new global route or within the given distance of the new global route, wherein said detailed re-routing the net in accordance with the new global route without regard to at least one of those of the nets within the new global route or within the given distance of the new global route comprises, detailed re-routing the net based, at least in part, on the at least one of those nets within the new global route or within the given distance of the new global route being removed or being marked for disregarding; and re-routing the at least one of those of the nets within the new global route or within the given distance of the new global route after completion of the detailed re-routing of the net.
