Abstract
The present invention comprises a method of optimizing a circuit design having a plurality of library cells. In one embodiment, the method includes the steps of providing a plurality of logically equivalent cells that vary in at least one design parameter, the plurality of logically equivalent cells having a relatively continuous spectrum of values of one of the design parameters, evaluating a selected characteristic of the circuit design; and replacing a cell in the circuit design with a cell an equivalent cell.
