摘要:
A method, system, and computer program product for coupled noise timing violation avoidance in detailed routing of an integrated circuit design are provided. The method includes calculating a noise induced timing violation sensitivity (NITVS) metric for nets in the integrated circuit design as a measure of sensitivity to a timing violation relative to a coupled noise delay adder, prioritizing routing isolation as a function of the NITVS metric for each of the nets to avoid coupled noise timing violations, and outputting the routing isolation priority.
