交通燈信號控制設計說明

1、 EDA技術實驗報告冊班級：姓名：學號：指導教師：開課時間: 2013 至2014 學年第 1 學期16 / 18實驗名稱交通燈信號控制設計實驗時間2013年12月05日姓 名實驗成績一、實驗目的1.掌握VHDL語言的基本結構。2.掌握VHDL層次化的設計方法。3.掌握VHDL基本邏輯電路的綜合設計應用。二、實驗設備計算機軟件：Quartus IIEDA實驗箱。主芯片：EPM7128SLC84-15或EP1K100QC208-3。下載電纜，導線等。三、實驗容設計并調(diào)試好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、支干道各設一個綠、黃、紅指示燈，兩

2、個顯示數(shù)碼管。2.主干道處于常允許通行狀態(tài)，而支干道有車來時才允許通行。當主干道允許通行亮綠燈時，支干道亮紅燈。而支干道允許通行亮綠燈時，主干道亮紅燈。3.當主、支干道均有車時，兩者交替允許通行，主干道每次放行45S，支干道每次放行25S，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。要求編寫交通燈控制器電路邏輯圖中的各個模塊的VHDL語言程序，并完成交通燈控制器的頂層設計，然后利用開發(fā)工具軟件對其進行編譯和仿真，最后要通過實驗開發(fā)系統(tǒng)對其進行硬件驗證。（一）編寫交通燈控制器JTDKZ模塊的VHDL程序，并對其進行編譯和仿真，初步驗證設計的正確性。LIBRAR
