Abstract:
A computer-implemented method comprising steps of:(A) identifying a first signal net in a first layer of an integrated circuit design; (B) identifying a second signal net in a second layer of the integrated circuit design; (C) determining whether at least one portion of the second signal net is within a threshold distance of the first signal net; (D) if it is determined that at least one portion of the second signal net is within the threshold distance of the first signal net, measuring the aggregate length along the first signal net that is within the threshold distance of the second signal net; (E) determining whether the measured length is at least as great as a threshold length; and (F) notifying a user that the second signal net is a neighbor of the first signal net if it is determined that the measured length is at least as great as the threshold length.
