Area-Driven White Space Distribution for Detailed Floorplan Design

In this paper, based on the LB-packing-based property in an LB-compact floorplan, some white space for advanced design requirement is considered By using the grouping concept of the block and the necessary space, the white space in a floorplan is redistributed to minimize the final floorplan area with satisfying all the space requirements. After running our proposed area-driven white space distribution, the experimental results show that the area increase is 1.4%~7.2% based on 4.2%~11.2% space requirement for the tested benchmarks in reasonable time. Clearly, the proposed LB-packing-based approach can redistribute the original white space to satisfy most of the space requirements.
