SYSTEM AND METHOD FOR EMPLOYING SIGNOFF-QUALITY TIMING ANALYSIS INFORMATION CONCURRENTLY IN MULTIPLE SCENARIOS TO REDUCE TOTAL POWER WITHIN A CIRCUIT DESIGN

摘要

A system is described that analyzes timing of a design and conditionally replaces values of a cell to lower total power within circuit paths having a positive timing margin. The system includes a computing device that includes a memory for storing modules and a processor that is operable to execute the modules. The modules cause the processor to conditionally replace a first semiconductor characteristic with a second semiconductor characteristic associated with a cell in a path of a circuit design and estimating a delay and a slack of the path based upon the first semiconductor characteristic. The modules also cause the processor to determine whether the second semiconductor characteristic causes a timing violation with respect to the path and causes conditional replacement of the second semiconductor characteristic with a third semiconductor characteristic until the timing violation is removed.
