ABSTRACT:
A method of determining whether voltage from an aggressor net exceeds a voltage threshold on a victim net design in an integrated circuit design. Probabilistic noise from the aggressor net on the victim net is calculated. The probabilistic noise is checked against the voltage threshold, and the victim net design is passed when the probabilistic noise does not exceed the voltage threshold. When the probabilistic noise does exceed the threshold, then an effective noise at a desired mean time to failure is computed, and the effective noise is checked against the voltage threshold. The victim net design is passed when the effective noise does not exceed the voltage threshold, and failed when the effective noise does exceed the threshold.
