System and method for employing signoff-quality timing analysis information concurrently in multiple scenarios to reduce dynamic power in an electronic circuit and an apparatus incorporating the same

Abstract

A dynamic power recovery system and method are disclosed herein. Additionally, an EDA tool and apparatus configured to perform dynamic power recovery are disclosed. In one embodiment, the system includes: (1) a power recovery module configured to carry out an instance of an initial power recovery process in each of multiple scenarios concurrently, the initial power recovery process including making first conditional downsizing of cells in at least one path in a circuit design with lower dynamic power cells and estimating a delay and a slack of the at least one path based on the first conditional downsizings and (2) a speed recovery module associated with the power recovery module and configured to carry out a speed recovery process in each of the multiple scenarios concurrently, the speed recovery process including determining whether the first conditional downsizings cause a timing violation with respect to the at least one path and making second conditional upsizings with higher dynamic power cells until the timing violation is removed.
