Abstract:
1. A method of re-routing an interconnection array, said method comprising: using a timing analysis tool with noise analysis capabilities to identify a first net, from a plurality of nets in said interconnection array, that has a first switching behavior and fails a timing requirement and further to identify a second net, from said plurality of nets, that has a second switching behavior, that is parallel to and adjacent to one side of said first net, and that is capacitively coupled to said first net, wherein an impact of coupling capacitance between said first net and said second net on said first switching behavior causes said first net to fail said timing requirement; selecting a third net that has a third switching behavior different from said second switching behavior; and re-routing said second net and said third net such that said second net and said third net are crossed and such that sections of both said second net and said third net are parallel to said one side of said first net, are adjacent to said one side of said first net, and are capacitively coupled to said first net, wherein a combined impact of coupling capacitances between said first net and said sections on said first switching behavior is reduced as compared to said impact of coupling capacitance between said first net and said second net alone.
