代碼功能：

十字路口交通燈控制器的VHDL設計(每班21號以后的單號)

設計要求:利用硬件描述語言和FPGA器件,設計實現(xiàn)一個由一條主干道和一條支干道的匯合點形成的十字交叉路口的交通燈控制器,具體要求如下：

(1)主、支干道各設有一個綠、黃、紅指示燈,兩個顯示數(shù)碼管。

(2)在主干道和支干道的兩個方向上各設有一組綠、黃、紅交通燈,其中一個方向是綠燈、黃燈、紅燈,另一個方向是紅燈、綠燈、黃燈。

(3)數(shù)碼管以倒計時的方式顯示允許通行或禁止通行的時間,主干道每次放行40s60s70s,支干道每次放行20s30s40s50s,在每次由亮綠燈變成亮紅燈的轉(zhuǎn)換過程中要亮5s的黃燈作為過渡,并進行減計時顯示,時鐘信號由實驗箱上50MHz分頻得到1H。

(4)設置交主干道優(yōu)先通行電路(選做

各放行定時器的實體名為:XXX放行時間,XXX為自己姓名的首字母。

任務學號對應:21、23、25號選(70150);27、29、31選(60140)33、35、37-選(5030);39、41、43選(40120)。
