Multi-FPGA prototyping is widely used for modern VLSI verification, but the limited number of inter-FPGA connections in a multi-FPGA system may cause routing failures. As result, time-division multiplexing (TDM) technique adopted to increase its resource utilization by transmitting multiple signals through same channel. Due large signal delay between FPGA pairs, however, performance such greatly depends on quality. In this paper, we propose TDM-based system-level algorithm simultaneously...
