Electronic design automation object placement with partially region-constrained objects

摘要

A global placer receives a plurality of regions, each region occupying a sub-area of a design area. receives a plurality of movebound objects, each movebound object associated with a region. The global placer receives a plurality of unconstrained objects, each unconstrained object associated with no region. The global placer receives a tolerance, wherein the placement tolerance defines a coronal fringe to at least one region. The global placer initially placing the plurality of movebound objects and unconstrained objects. The global placer iterates over objects without preference to region-affiliation to select an object, wherein the objects are comprised of the plurality of movebound objects and plurality of unconstrained objects. The global placer determines whether movebound object is within the tolerance of a region associated with the movebound object.
