BOUNDARY BASED POWER GUIDANCE FOR PHYSICAL SYNTHESIS

摘要

A method and system to obtain a physical design of an integrated circuit from a logical design are described. The system includes a memory device to store a logical design, and a processor to execute a synthesis engine. The processor performs a baseline synthesis to obtain a baseline physical design using timing constraints and an overall power budget, computes power assertions, performs a re-synthesis using the timing constraints and the power assertions to obtain a new physical design, compares the new physical design with the baseline physical design to determine a degradation of the new physical design in comparison with the baseline physical design, reduces a weighting of the power assertions relative to the timing constraints based on the degradation, and iteratively performs the re-synthesis, compares the new physical design with the baseline physical design, and reduces the weighting until the degradation is below a threshold value.

1. A system to obtain a physical design of an integrated circuit from a logical design, the system comprising:
a memory device configured to store a logical design; and a processor configured to execute a synthesis engine, the processor being further configured to:
perform a baseline synthesis to obtain a baseline physical design using timing constraints and an overall power budget;compute power assertions;perform a re-synthesis using the timing constraints and the power assertions to obtain a new physical design;compare the new physical design with the baseline physical design to determine a degradation of the new physical design in comparison with the baseline physical design;reduce a weighting of the power assertions relative to the timing constraints based on the degradation; anditeratively perform the re-synthesis, compare the new physical design with the baseline physical design, and reduce the weighting until the degradation is below a threshold value.
