The experiment required to complete the task in the role of the clock signal through the input keys displays the corresponding key on the digital tube. In the experiment, the digital clock as scan clock 1KHZ with four toggle switch as input, when the four toggle switch is set when a binary number, display its hexadecimal value in the digital tube. Experimental tank toggle switch with FPGA interface circuit, and a toggle switch FPGA pins are connected to a test done a detailed explanation, not repeat them here.
