1. A method of designing an integrated circuit (“

  • IC”

    ) layout, said method comprising;

    processing the IC layout with a Manhattan based placement program to produce an initial placement of the IC layout;

    processing said initial placement with a non Manhattan based post processor to produce a non Manhattan based placement of the IC layout, wherein the processing of the initial placement is performed before a non Manhattan based routing; and

    performing the non Manhattan based routing after processing the initial placement with the non Manhattan based post processor, wherein the non Manhattan based routing defines routes for a plurality of nets of the IC layout that did not have defined routes after the processing by the non Manhattan based post processor of the initial placement.
