With the fast increase of the scale of VLSI and the development of multi-core technology, the research on parallel routing algorithm has been brought into focus. In this paper, we introduce a novel parallel routing algorithm, in which we design a region partition strategy with the concerns about load balance. In our approach, the region is divided into well-proportion sub-regions, so that the parallel tasks could be completed approximately simultaneously. Besides, we implement the algorithm by multi-threading technology and the parallel tasks are scheduled with the task farm. Experimental results clearly demonstrate the efficiency and high speedup of our approach, which reaches 1.5 times or more.
