US 10,242,149 B2 · Enhancing integrated circuit noise performance

Abstract

A method, system, and computer program product for enhancing integrated circuit noise performance. The method is for arranging target wires in a target region, the method including: for each wire in the target wires, obtaining a signal jump interval with respect to each of the other wires in the target wires, wherein the signal jump interval of one wire with respect to a further wire is a time interval between occurrence of signal jump on the one wire and occurrence of signal jump on the further wire; calculating a corresponding time influence factor based on the signal jump interval, wherein the time influence factor is a decreasing function of the signal jump interval; and arranging the target wires in the target region based on the time influence factor. Coupling noise between wires may be reduced according to the technical solution of an embodiment of the present invention.

A method comprising:

obtaining a signal jump interval between each wire in a set of target wires, wherein the signal jump interval of one wire in the set of target wires with respect to another wire in the set of target wires is equal to a time interval between an occurrence of a signal jump on the one wire and an occurrence of a signal jump on the other wire;
calculating a corresponding time influence factor based on the signal jump interval, wherein the time influence factor is a decreasing function of the signal jump interval;
for each wire in the set of target wires, calculating a total time influence factor based on a sum of its signal jump intervals with each wire in the set of target wires;
