Design of Traffic Light Controller System Based on Verilog HDL

As a common language for the description of hardware, Verilog HDL is widely applied in circuit designing. The design description can be supportted by different tools and implemented by different devices.In this paper, the process of designing traffic light controller system by the Verilog HDL topdown design method is presented, which has made the road traffic work well, the design of this system has shown the readability, portability and easily understanding of Verilog HDL as a hard description language. Circuit synthesis and simulation are performed by Xilinx ISE6.02 and ModelSim5.6. The program can be used in the truly traffic light controller system by downloading to the FPGA chip.
