摘要:
The process of laying out a floorplan for a clock control distribution network in an integrated chip design is simplified and the efficiency of a staging network created is improved. Rather than manually create the staging network in HDL or as a network description table while looking at a picture of the chip floorplan in a Cadence Viewer, an automated method which runs in the Cadence environment uses an algorithmic approach to the problem of maximizing the utilization of staging latches, eliminating unnecessary power and area usage. Efficiency is maximized by updating the Physical Layout directly with the staging solution arrived at by the algorithm.
