Patent ID: 7685549

Claim:
A method of obtaining an optimal set of coupled aggressors for a given victim in an integrated circuit (IC) chip design to enhance said IC chip design, said given victim comprising a single noise event, the method comprising a) determining functional groups for said single noise event that relate the coupled aggressors of said single noise event to each other; b) for each aggressor to said single noise event, determining the aggressor's contribution to said single noise event; c) determining a set of essentially worst coupled aggressors that satisfies constraints from said functional groups based on a measured contribution of each aggressor on said single noise event; d) providing by a computer said optimal set of coupled aggressors using said set of essentially worst aggressors to said single noise event; and e) modifying said IC chip design by supplying thereto results from said optimal set of coupled aggressors to a timing analysis of said IC design.
