基于VHDL语言的交通灯控制器设计

Design of Traffic Light Controller Based on VHDL

传统的交通灯控制器多数由单片机或PLC来实现,文中介绍了基于VHDL硬件描述语言进行交通灯控制器设计的一般思路和方法。选择XILINX公司低功耗、低成本、高性能的FPGA芯片,采用ISE5.X和MODELSIMSE 6.0开发工具进行了程序的编译和功能仿真。最后给出了交通灯控制器的部分VHDL源程序和仿真结果,仿真结果表明该系统的设计方案正确。

Traffic light controller is usually developed by micro processor or PLC. This paper introduces the general design methods of tragic light controller base on VHDL（ hardware description language）, the FPGA chip of XILINX Corporation was chosen with the low power loss, the low cost and the high performance, the XILINX ISE5. X and MODELSIM 6.0 development tools was used to compile and stimulate. Finally, The VHDL source programmer and simulating results of traffic light controller are given. The simulating results show that the design method is correct.
