基于FPGA的交通灯控制器的设计与实现

The design and implementation of traffic light control system based on FPGA

以Quartus II软件为设计平台,采用Verilog HDL语言,运用自上而下的模块化设计思路完成了十字路口的交通灯控制器设计,最后通过编译、仿真并下载至FPGA芯片中验证了其设计的正确性。该控制器较传统交通灯控制电路具有外围电路少、开发周期短、功能拓展灵活及带有紧急情况禁止所有车辆通行功能等优点。

Based on the design platform of Quartus II software, using Verilog HDL language, and applying the idea of top-down modular design, the design of traffic light controller for crossroads was completed. Through compiling, simulation and download to the FPGA chip, the correctness of the design was validated. Compared with the traditional traffic light circuit, the controller is featured by peripheral circuit, short development cycle, flexible extension of function,and prohibition of vehicle in emergency, etc.
