WebAug 16, 2024 · This technique quasi adds extra delay to the clock path towards the FPGA (the CLK_fpga_m (/M) in the constraint file). If the value of the clock_shift above equals the previously approximated ~7ns, the value of the tco will be a simple output delay. The ~7ns of the clock_shift has to be converted to phase for Xilinx's clock wizzard.
