Dynamic power gating applicable to FPGA can reduce the power consumption effectively. In this paper, we propose a sophisticated routing architecture for a region oriented FPGA which supports dynamic power gating. This is the first routing solution of dynamic power gating for coarse-grained FPGA. This paper has 2 main contributions. First, it improves the routing resource graph and routing architecture to support special routing for a region oriented FPGA. Second, some routing channels are made wider to avoid congestion. Experimental result shows that 7.7% routing area can be reduced compared with the symmetric Wilton switch box in the region. Also, our proposed FPGA architecture with sophisticated PR can reduce the power consumption of the system implemented in FPGA.
