Abstract
Coupled noise from at least one out-of-context aggressor net of an integrated circuit design is computed for an out-of-context victim net. The nets are out-of-context with respect to a hierarchical noise analysis of the integrated circuit design. At least one of the nets is a continuation of a path which extends to at least one in-context portion of the integrated circuit design. An aggressor signal timing window is derived for the at least one out-of-context aggressor net; a victim signal timing window is derived for the out-of-context victim net; and a timing window and noise analysis is completed with the aggressor signal timing window and the victim signal timing window. The aggressor window is derived as a function of required arrival time of the at least one out-of-context aggressor net and/or the victim window is derived as a function of required arrival time of the out-of-context victim net.
