It's a trend to consider power supply integrity at early stage to improve the design quality. In this paper, we propose a novel algorithm to optimize floorplan together with P/G network. Compared with previous methods, our algorithm can search the floorplan space more efficiently and therefore lead to better results. Further, we also propose a smart heuristic method to build P/G mesh grid with optimized topology. Experimental results show our method can speedup the floorplanning process by about 10 times and reduce the routing area of P/G network while maintaining the floorplan quality and P/G integrity.
