  • Timing refinement re-routing
    Patent number: 8635577
    Abstract: A design tool can automatically improve timing of nets of a fully routed physical design solution. Nets of a netlist are evaluated against a plurality of re-routing criteria to identify the nets that satisfy at least one of the plurality of re-routing criteria. For each of the nets that satisfy at least one of the plurality of re-routing criteria: several operations are performed. The net is globally re-routed to determine a new global route for the net. Those of the nets that are within a given distance of the new global route are identified. The net is detail re-routed in accordance with the new global route without regard to those of the nets within the given distance of the new global route. Those of the nets within the given distance of the new global route are re-routed after completion of the detailed re-routing of the net.
