DE0开发板交通灯控制器红绿灯时间可配VHDL_电路方案

名称：DE0开发板交通灯控制器红绿灯时间可配（代码在文末下载）

软件：QuartusII

语言：VHDL

代码功能：

要求：设计一个十字路口交通信号灯的控制电路。

要求红、绿灯按一定的规律亮和灭，并在亮灯期间进行倒计时，且将运行时间用数码管显示出来。

绿灯亮时，为该车道允许通行信号，红灯亮时，为该车道禁止通行信号。

该代码的主路支路通行时间可根据要求自行设置，默认主路绿灯25s，主路黄灯5s，支路绿灯20s，支路黄灯5s。

设置时间时，在顶层文件找到以下代码，修改对应时间的二进制值即可。

--设置时间，可自行修改时间,
G1_time?<=?"00011001";--主路绿灯25s
Y1_time?<=?"00000101";--主路黄灯5s
G2_time?<=?"00010100";--支路绿灯20s
Y2_time?<=?"00000101";--支路黄灯5s

本代码已在DE0开发板验证，开发板如下：
