Abstract: Verilog HDL language to use top-down design method the design of traffic light control system, to achieve the normal operation of the Road Traffic. Highlights the Verilog hardware description language as a good readability, portability and easy to understand, etc., through the Quartus II design software to complete the process of simulation. This process by downloading to the FPGA chip can be used in practical control system of traffic lights.
Key words: Verilog HDL; EDA; traffic light; Quartus II; simulation
