Application of timing-window and miller-factor in timing analysis with crosstalk

The methods of timing-window and miller-factor are researched, which are used in static timing analysis to filter out the crosstalk-situations that have little contribution to the signal delay. And take use of miller-effect to decouple the coupling capacitance between wires, to compute more accurate delays. According to the signal transitions between the coupling points, a more accurate miller-factor is computed, which is used in the following delay computation with crosstalk. A fast and accurately estimation of the effect ofcrosstalk on delay. These ways will help designers find out the effects and solve the violations caused by crosstalk early in design phase.
