自動售貨機設(shè)計與實現(xiàn)

深圳大學實驗報告課程名稱：數(shù)字系統(tǒng)現(xiàn)場集成技術(shù)實驗項目名稱：自動售貨機設(shè)計與實現(xiàn)學院：信息工程學院 專業(yè)：集成電路設(shè)計與集成系統(tǒng) 指導教師： 報告人：學號：班級：同組人：學號：班級：實驗時間：實驗報告提交時間：一、實驗?zāi)康?、進一步熟悉ISE軟件的使用，熟悉FPGA開發(fā)流程；2、掌握編寫fpga代碼的步驟，學會繪制ASM圖；3、學會調(diào)用ip核實現(xiàn)系統(tǒng)的設(shè)計。二、實驗設(shè)備1、裝有ISE軟件的PC機一臺；2、nexys2開發(fā)板一塊。三、實驗內(nèi)容與要求設(shè)計一個秒表基本要求：該實驗為團隊協(xié)作，2人一個小組。可以對3種不同種類的貨物進行自動售貨,價格分別為A=4.00,B=2.50,C=1.00。售貨機可以接受10元,5元,1元三種硬幣(即有三種輸入信號SY,WY,IY),并且在7段數(shù)碼管(二位代表元,一位代表角)顯示已投入的總錢數(shù),選擇貨物的輸入信號Ia,Ib,Ic,輸出指示信號為Sa,Sb,Sc分別表示售出相應(yīng)的貨物,同時輸出的信號yuan,jiao代表找零，并顯示在7段數(shù)碼管上。高級要求（可選）：VGA顯示3種貨物圖片及其價格，鼠標點擊購買數(shù)量（1-9）后顯示總價，安規(guī)格說明2中的button2-button4輸入硬幣，VGA顯示已投入的總錢數(shù)，鼠標點擊購買后，顯示找零數(shù)目，購買物品閃爍，交易完成。規(guī)格說明：1. 按一下button1按鈕，表示購買貨物A，第一個LED燈亮；按兩下button1按鈕，表示購買貨物B，第二個LED燈亮；按三下button1按鈕，表示購買貨物C，第三個LED燈亮，同時7段數(shù)碼管顯示所要購買貨物的價格。2. LED燈亮后，開始輸入硬幣。button2按一下，輸入10元，按兩下，輸入二十元，以此類推；Button3按一下輸入5元，按兩下輸入10元，以此類推；button4按一下輸入1元，按兩下輸入2元，以此類推。7段數(shù)碼管顯示已投入的總錢數(shù)，再次按下button1鍵，7段數(shù)碼管顯示找零數(shù)目，同時指示貨物的LED燈熄滅。3. 如果投入的錢幣不夠就按下button1鍵確認購買，數(shù)碼管顯示“ER”。4. 本實驗使用FPGA板：nexys2（建project時，需要選擇該芯片的型號）。四、實驗步驟1、設(shè)計系統(tǒng)框圖，設(shè)計采取自上而下的設(shè)計方案，整個秒表系統(tǒng)的原理圖如下所示。主要包括四個模塊——分頻模塊、vga協(xié)議模塊、鼠標、vga數(shù)據(jù)處理模塊。而vga數(shù)據(jù)處理模塊里面又有好幾個模塊–有vga數(shù)碼管顯示模塊，顯示地址模塊（用來生成地址給rom的），還有好多各rom的顯示模塊，板子按鍵的處理模塊以及鼠標按鍵的處理模塊。總的RTL圖分頻器Vga協(xié)議Vga數(shù)據(jù)處理MouseVga數(shù)據(jù)處理總體2、所編寫的代碼如下。------------------------頂層文件----程序主代碼------------------------------------------
