Apparatus and methods for optimization of integrated circuits

摘要

A system for computer-aided design (CAD) of an integrated circuit (IC) uses a computer. The computer is configured to optimize placement, routing, and/or region configuration of the integrated circuit (IC) by maximizing a number of low-power regions in the integrated circuit (IC).

主权项

1. A system for computer-aided design (CAD) of an integrated circuit (IC) having a plurality of regions operable in a low-power mode and a high-speed mode, the system comprising:
a computer that is configured to:
set each region in the plurality of regions in an integrated circuit (IC) to operate in either the low-power mode of operation or the high-speed mode of operation in order to optimize timing and power consumption of the integrated circuit (IC);perform a first timing analysis;compute a gain for each region in the plurality of regions, wherein the gain is a function of a negative slack improvement that would result from changing the at least one region to the high-speed mode of operation; andgenerate a configuration bitstream that is loaded onto the integrated circuit and that changes at least one region in the plurality of regions to the high-speed mode of operation based on the computed gain.
