數(shù)字邏輯實驗報告

1、北京郵電大學數(shù)字電路與邏輯設計實驗報告實驗題目：擲骰子游戲電路的設計與實現(xiàn)學生姓名： 班級：學號： 序號：目錄一、 設計課題的任務要求二、 系統(tǒng)設計三、 仿真波形及波形分析四、 源程序五、 功能說明及資源利用情況六、 故障及問題分析七、 總結和結論一、 設計課題的任務要求設計并實現(xiàn)一個擲骰子游戲電路。 基本要求： 1、 電路可供甲乙二人游戲，游戲者甲使用的按鍵為 BTN0，游戲者乙使用的按鍵為 BTN1。2、 每按一次按鍵，代表擲一次骰子，可隨機得到 16 范圍內(nèi)的兩個數(shù)字。 3、 甲乙按鍵產(chǎn)生的隨機數(shù)字分別用數(shù)碼管 DISP0-DISP1、DISP2-DISP3 顯示,并用 DISP7 顯示

2、比賽局數(shù)，比賽結束用 8×8 點陣顯示獲勝方，并伴有聲音效果。4、 具體游戲規(guī)則如下： （1） 第一局比賽，甲乙依次各按一次按鍵，按鍵所得兩數(shù)之和為7或11者勝；若無 人取勝，則進行第二局比賽； （2） 第二局比賽，甲乙每人各按一次按鍵，按鍵所得二數(shù)之和與第一局比賽相同者獲 勝，若無人獲勝，則進行第三局比賽，重復進行步驟（2），直到出現(xiàn)勝者為止。 （3） 游戲局數(shù)最多進行六局。在第六局比賽時，若重復進行步驟（2）仍未出現(xiàn)勝者， 以按鍵所得兩數(shù)之和最大者為獲勝方。 提高要求： 1、 增加多人游戲的功能，數(shù)碼管可分時記錄顯示每個游戲者的骰子點數(shù)。 2、 點陣顯示增加游戲開機動畫、結束動畫

3、，并伴有樂曲播放。 3、 自擬其它功能。二、系統(tǒng)設計1、設計思路：按照實驗要求，使用狀態(tài)機分別表示游戲的不同狀態(tài)；使用分頻器來控制時鐘；控制器實現(xiàn)具體的游戲規(guī)則；8*8LED點陣來顯示勝負；數(shù)碼管顯示局數(shù)和甲乙擲出的隨機數(shù)；隨機數(shù)用一到六的循環(huán)產(chǎn)生。在編譯時采用元件例化來生成各自的模塊。流程圖如下 顯示2、總體框圖：控制器分頻器防抖器輸入3、分塊設計：分別包括分頻器、防抖器、隨機數(shù)的產(chǎn)生、判斷器、譯碼器和顯示器等模塊，綜合起來實現(xiàn)所要求的功能。分頻器：防抖器：隨機數(shù)的產(chǎn)生： 判斷器： 譯碼器： 顯示器：三、 仿真波形及波形分析根據(jù)甲先乙后的順序進行仿真如下：從仿真中可以看出隨機數(shù)的產(chǎn)生，若時間
