Abstract
A preliminary static timing analysis run is performed to calculate the delay and slew as well as timing windows for each net in the design, followed by coupling analysis for each given aggressor-victim combination, and to calculate the noise effect on the timing of victim net. Given a set of functional groups that relate the coupled aggressors to each other, the worst set of aggressors are calculated that satisfy the constraints from the functional groups, based on the calculated impact of each aggressor on the victim. Similarly the set of aggressors which contribute to the maximum amount of inductive coupling noise effect on timing are calculated. Furthermore, the coupling noise impact of the reduced set of aggressors on the given victim line and adjust the delay value calculated in the preliminary static timing analysis run.
