发明名称 DENSITY-BASED AREA RECOVERY IN ELECTRONIC DESIGN AUTOMATION
摘要 Some embodiments provide techniques and systems for improving the efficiency of area recovery in an electronic design automation (EDA) flow. During operation, the system determines a utilization of a region from a set of regions in a design floorplan. Next, the system performs area recovery (e.g., by using a processor) on the region based at least on the utilization. Specifically, the system can overlay the design floorplan with a grid, wherein the grid comprises a set of grid cells and uses the grid cells as the set of regions. The grid can be associated with a predetermined number of rows and a predetermined number of columns. The system can determine the utilization of the region by calculating the utilization as a cell area of the region divided by a placement area of the region. The utilization can be incrementally calculated during the creation and optimization of the design.
