Abstract: Switch matrix is one of the most important structure in FPGA devices. In the paper, the switch matrix of FPGA is analyzed in details. The placement and routing is at first introduced for switch matrix modeling. During the simulation, analysis and optimization of the model performed, the relationship between the velocity and parameters is discussed. The results show that the switch matrix is of better performance after optimization.
