System and method for designing a circuit wherein a single timing analysis ensures adequate performance in multiple applications

A computer program product for designing a circuit comprising a plurality of conductors, the computer program product having a medium with a computer program embodied thereon, the computer program comprising:

• computer program code for applying a factor to resistance values of the conductors, thereby producing modified conductor resistance values, wherein the factor is computed dependent upon a determined performance difference between operation of the circuit at a selected first operating point, corresponding to a first circuit application, and a selected second operating point corresponding to a second circuit application;
• and
• computer program code for performing a timing analysis of the circuit at the first operating point using the modified conductor resistance values, thereby producing a result indicative of whether the circuit will operate correctly at the second operating point.

An apparatus for designing a circuit comprising a plurality of conductors, the apparatus comprising:

• means for applying a factor to resistance values of the conductors, thereby producing modified conductor resistance values, wherein the factor is computed dependent upon a determined performance difference between operation of the circuit at a selected first operating point, corresponding to a first circuit application, and a selected second operating point corresponding to a second circuit application;
• and
• means for performing a timing analysis of the circuit at the first opening point using the modified conductor resistance values, thereby producing a result indicative of whether the circuit will operate correctly at the second operating point.
