a novel minloop sb design to improve fpga routability
In this paper, we present a new design of a switch box of an FPGA that requires less channel width than conventional designs in routing the same circuit. The design, called a Minloop switch box, is based on the method of minimum-loop-size maximization in routing resources. Experimental results show that the Minloop switch box requires 17.7\%, 8.0\% and 2.4\% less channel width than the classic fabric of Disjoint, Universal and Wilton switch boxes, respectively.
