Abstract
The present disclosure is directed to a method and apparatus for dividing an integrated circuit design field into a plurality of congestion rectangles having user-selectable sizes. A routing congestion value is estimated for each congestion rectangle prior to routing interconnections within the design field. The congestion values are stored in machine-readable memory and are updated in response to wire changes within the design field.
