Traffic light controller is usually developed bymicro p rocessor or PLC. This paper introduces the gen2
eral design methods of traffic light controller base on VHDL ( hardware descrip tion language). the FPGA chip of XIL2
INX Corporation was chosen with the low power loss, the low cost and the high performance, the XIL INX ISE5. X
andMODELSIM 6. 0 development toolswas used to comp ile and stimulate. Finally, The VHDL source p rogrammer
and simulating results of traffic light controller are given. The simulating results show that the design method is cor2
