Method and apparatus for verifying signal timing of electrical circuits

摘要

The present invention is directed to a method and apparatus for accurately estimating signal delays of an electrical circuit by taking into account both resistance and capacitance of an interconnect network when determining both gate delays and interconnect delays of the circuit. Exemplary embodiments of the present invention, by providing a highly accurate estimate of signal delays, result in highly efficient, cost-effective electrical circuit design and fabrication. Further, a high degree of customer satisfaction can be realized because the possibility that a given electrical circuit will not comply with customer specified time constraints is minimal.
