Patent ID: 7216316

Claim:
A method for evaluating nets in a crosstalk noise analysis, comprising: selecting one timing window from a first net, wherein the first net includes a plurality of timing windows; selecting one timing window from a second net, wherein the second net includes a plurality of timing windows; analyzing characteristics of the one timing window from the first net and the one timing window from the second net to identify a timing window overlap presence between any of the plurality of timing windows associated with the first net and any of the plurality of timing windows associated with the second net, wherein the analyzing includes determining an offset if present between the one timing window from the first net and the one timing window from the second net, obtaining a remainder of an integer division between the offset and a greatest common divisor of periods of the first and second nets, and comparing the remainder to a duration of one of the timing windows selected from one of the first net and the second net; and flagging the first and second nets as having a potentially adverse crosstalk noise condition upon identification of the timing window overlap presence.
