Abstract
A method and apparatus for optimizing a circuit design having multi-cycle paths therein. In an exemplary embodiment, a circuit design having a number of multi-cycle paths may be optimized by: identifying at least one of the number of multi-cycle paths within the circuit design, and identifying the corresponding qualified clocks associated therewith; replacing selected ones of the corresponding clocks with replacement clocks; and optimizing the circuit design using the replacement clocks. By using a replacement clock that has a clock period equal to the corresponding clock, which is typically a qualified clock, a standard optimization tool may correctly optimize the circuit design.
