  • Symbolic constraint-based system for preroute reconstruction following floorplan incrementing
    Patent number: 6002857
    Abstract: The present invention includes a method for automatically reconstructing most of the power, ground and clock prerouting without significant user involvement. This enables several floorplans to be tried concurrently in a batch mode. The method automatically migrates many floorplans in increments to find the best result for each starting floorplan. The user is then free to select a floorplan that looks best from the candidates generated with all the special net routing patterns already considered and updated for each.
