A crosstalk analysis system that uses automatically extracted circuit timing information to calculate real-world crosstalk estimates. The crosstalk analysis system of the present invention improves the accuracy of crosstalk calculations by incorporating into the analysis automatically extracted inter-signal timing information. The present invention monitors a functional simulation run to automatically provide summary net activity time windows that are directly forward-annotated into a crosstalk analyzer. The crosstalk analyzer drastically reduces the number of crosstalk false alarms by avoiding summation of crosstalk noise between neighbor nets that switch out of phase with respect to each other.
