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；
⑨ 用两组开关代替传感器作为检测人员通过请求和车辆是否到来的信号。用红、绿、黄三种颜色的发光二极管作交通灯；
⑩ 要求显示时间，倒计时。-Through hardware descr iption language VHDL programming, traffic lights functional requirements are as follows:

② trunk road junctions equipped with staff through a request button (PQ), if there is a request message, the controller should be released, otherwise handled by default
③ Online control signal issued by the traffic control center, (Online = 1) if it is valid, trunk release, cross the intersection Controller "failure", Online = 0 crossroad controller resumes control over
