摘要：

This paper deals with the design and optimization of mesh-based power/ground network for cell-based VLSIs with macro cells. These macro cells absorb a lot of current, furthermore, the current that each pin of the macro cell absorbs is not known, which introduces a new problem to the design of power routing. This problem hasn't been discussed so far. In this paper, a new algorithm is presented to solve this problem. The algorithm includes 3 sub-algorithms: searching feasible solution, cutting branches and minimizing strap width. The algorithm has achieved the object which minimize the area of power straps with high running speed.
