ABSTRACT:
Method, system and program product for determining a critical area in a region of an integrated circuit layout using Voronoi diagrams and shape biasing. The method includes the steps of generating a biased Voronoi diagram based on a layout geometry of the region and incorporating a shape bias; and determining the critical area for the region using the biased Voronoi diagram.
