US Patent 7124381 Method of estimating crosstalk noise in lumped RLC coupled interconnects

A method for efficiently estimating crosstalk noise of high-speed VLSI interconnects models high-speed VLSI interconnects as lumped RLG coupled frees. An inductive crosstalk noise waveform can be accurately estimated in an efficient manner using a linear time moment computation technique in conjunction with a projection-based order reduction method. Recursive formulas of moment computations for coupled RC trees are derived taking into consideration of both self inductances and mutual inductances. Also, analytical formulas of voltage moments at each node will be derived explicitly. These formulas can be efficiently implemented for use in crosstalk estimations.
