摘要
伴随着中国经济的快速发展,城市规模越来越大,机动车辆越来越多,给城市交通带来了巨大压力。而传统交通灯控制系统是通过采用中小规模集成电路,或者是采用单片机和PLC等控制芯片进行设计,从而存在控制精度低、电路设计复杂、系统维护困难、成本居高不下等问题。本文采用FPGA的cyclone II芯片,用Verilog HDL硬件描述语言,通过Quartus II软件进行综合仿真,对各功能模块进行设计,然后通过连线组合各底层模块来实现顶层模块设计。
With the rapid development of China's economy,the increasing scale of the city,motor vehicles,more and more traffi c to the city brought tremendous pressure.Aimed at the traditional problems such as inaccurate control,complex peripheral circuits,infl exible program modifi cation and higher costs,the design traffi c light control systems adopt single chip microcomputer as a control chip,the system of each functional module is designed FPGA with Verilog hardware description language and Quartus II software platform.Each functional module component symbols is added,and then achieve top-level module design through the connection combination from each bottom-level module.
