Noise containment in a high wiring density multichip module

A methodology for containing coupled noise in a high wiring density multichip module (MCM) in which hundreds of nets interact with each other is outlined. TEM mode multi-conductor transmission line analysis and a time-based statistical technique are the basis for a sophisticated design analysis and which predicts the aggregate noise for each net. Nets exceeding a predetermined voltage limit, set by the receiver noise margin, are reworked iteratively until technology constraints are satisfied.<<ETX>>
