摘　　要：基于硬件电路设计软件化的思想,根据路口交通灯控制功能要求,以可编程逻辑器件(FPGA)为硬件基础,以有限状态机为设计基础,通过对系统状态及其转移关系的定义,运用多进程方式描述硬件模块的逻辑关系,用VHDL语言编程实现了交通灯控制系统,经仿真,并在实验箱上进行功能测试,正确实现了预期功能。仅用一片可编程逻辑器件,即完成需要的控制功能,设计思路清晰,实现过程灵活。Based on the thought of hardware electric circuit design turned to software,it was put forward to design about traffic light control system with FPGA and finite state machine according to control requirements.Through defining the system states and their transfer relation,the hardware modules logic relation was described with multi-process.Under simulation using VHDL,the function test in the experiment box carried on.The expectation function carried out correctly.Only using one piece of FPGA,the control function of demand is completed.It is showed that the design way is clear and the process is flexible.
