ABSTRACT:
A method and system are provided for analyzing process window compliance of an integrated circuit design. Aspects of the present invention include identifying layout pattern configurations that have process windows that fail to meet respective local performance specifications; searching for any layout pattern configurations in a design that substantially match any of the identified layout pattern configurations; and modifying any matching layout pattern configurations found in the design to make the layout pattern configurations compliant with their respective process windows.
