Description: 通过硬件描述语言VHDL编程，实现交通灯功能，要求如下：
① 车辆传感器（C），检测车辆通行情况，用于主干道的优先权控制；
② 主干道公路路口安装有人员通过请求按钮（PQ），一旦有请求信息，控制器应按放行处理，否则按默认方式处理；
③ Online控制信号由交通控制中心发出，（Online=1）一旦它有效，则主干道放行，十字交叉路口控制器“失效”，Online=0十字交叉路口控制器恢复控制权；
④ 当次干道公路无车时，始终保持次干道公路红灯亮，主干道绿灯亮；
⑤ 当次干道公路有车时，而主干道通车时间已经超过它的最短通车时间时，禁止主干道通行，让次干道公路通行。主干道最短通车时间为25s ；
⑥ 当次干道公路和主干道都有车时，按主干道通车25s，次干道公路通车16s交替进行；
⑦ 不论主干道情况如何，次干道公路通车最长时间为16s；
⑧ 在每次由绿灯亮变成红灯亮的转换过程中，要亮5s时间的黄灯作为过渡；
