3、程設(shè)計評分表.一、16選1選擇器的主要功能數(shù)據(jù)選擇器是常用的組合邏輯部件之一。它由組合邏輯電路對數(shù)字信號進行控制來完成比較復(fù)雜的邏輯功能。它有若干個數(shù)據(jù)輸入端D0、D1、.，若干個控制輸入端A0、A1，.和一個輸出端Y0。數(shù)據(jù)選擇是指經(jīng)過選擇，把多個通道的數(shù)據(jù)傳送到唯一的公共數(shù)據(jù)通道上去。它的功能相當(dāng)于一個多個輸入的單刀多擲開關(guān).因此數(shù)據(jù)選擇器又稱多路轉(zhuǎn)換器或多路開關(guān)。數(shù)據(jù)選擇器(MUX)的邏輯功能是在控制輸入端加上適當(dāng)?shù)男盘枺瓤蓮亩鄠€輸入數(shù)據(jù)源中講所需的數(shù)據(jù)信號選擇出來，送到輸出端。1. 函數(shù)真值表 輸入輸出ABCDE000000010010001101000101011001111000

5、已全部完成，能夠完成預(yù)期的功能，在本課題的設(shè)計中體現(xiàn)了VHDL覆蓋面廣，描述能力強，是一個多層次的硬件描述語言及PLD器件速度快，使用方便，便于修改等特點。由于時間有限和經(jīng)驗是平的欠缺，不足之處還望老師予以指正。在這一周里我們再次熟悉和增強了對VHDL語言的基本知識，熟悉利用VHDL語言對常用的的組合邏輯電路和時序邏輯電路編程，把編程和實際結(jié)合起來。VHDL硬件描述語言打破了硬件和軟件設(shè)計人員之間互不干涉的界限，可以使用語言的形式來進行數(shù)字系統(tǒng)的硬件結(jié)構(gòu)、行為的描述，直接設(shè)計數(shù)字電路硬件系統(tǒng)。通過編程、下載后，該芯片已經(jīng)具備了原來需要使用復(fù)雜的數(shù)字電路實現(xiàn)的功能；更加了解和加深了對編制和調(diào)試程

6、序的技巧，進一步提高了上機動手能力，培養(yǎng)了使用設(shè)計綜合電路的能力，養(yǎng)成了提供文檔資料的習(xí)慣和規(guī)范編程的思想。本次的課程設(shè)計將各個單一的模塊實現(xiàn)其功能后，學(xué)會通過原理圖或頂層文件把各模塊連接。課設(shè)注重的不僅是把理論知識鞏固，而且應(yīng)把理論和實際相結(jié)合，把知識應(yīng)用到生活中。課設(shè)時間不長，要在短時間內(nèi)完成絕非個人力量能達到的，要學(xué)會集眾人之精華，還要善于利用已有的工具為己服務(wù)，開拓思維。課設(shè)讓我們認(rèn)識到所學(xué)本科知識的真正實用性，只是這門課開始研究的第一步。一、JK觸發(fā)器的主要功能JK觸發(fā)器是數(shù)字電路觸發(fā)器中的一種電路單元。JK觸發(fā)器具有置0、置1、保持和翻轉(zhuǎn)功能，在各類集成觸發(fā)器中，JK觸發(fā)器的功能最

7、為齊全。在實際應(yīng)用中，它不僅有很強的通用性，而且能靈活地轉(zhuǎn)換其他類型的觸發(fā)器。由JK觸發(fā)器可以構(gòu)成D觸發(fā)器和T觸發(fā)器。1. 特性方程2.真值表CPJK0xx000xx1110000100111010010110110011101111101111103.邏輯電路圖二、詳細設(shè)計1.新建工程管理2. 輸入文本語言程序進行編譯3.編譯成功，選擇波形編輯器功能4.對應(yīng)結(jié)點5.形成綜合編譯后網(wǎng)表三、進行程序仿真調(diào)試1.給定輸入信號2.波形仿真測試成功3. 生成波形圖四、心得體會總結(jié) 成了16選1選擇器的電路設(shè)計之后，便開始了JK觸發(fā)器的課題設(shè)計，因為前一個課設(shè)的完成，使我對于QUARTUS軟件的使用有了

8、一定的了解，所以在這個實驗設(shè)計的時候也輕松了很多。在完成JK觸發(fā)器的課設(shè)時，我只要參看書本上的JK觸發(fā)器的設(shè)計思路完成源代碼的編寫即可，然后就是上機測試編寫的程序，結(jié)果在測試時，出現(xiàn)了錯誤，但是在老師和同學(xué)的幫助下，我終于解決了它，然后編譯、仿真。雖然第二個課設(shè)沒有花費很多的時間，但是我還是發(fā)現(xiàn)，在實際設(shè)計中，僅僅擁有書本上的理論性知識是遠遠不夠的，還要把知識與實際操作相結(jié)合，才能更加了解這門課程的精奧之處。課程設(shè)計結(jié)束了，但是從中學(xué)到的知識會讓我受益終身。發(fā)現(xiàn)、提出、分析、解決問題和實踐能力的提高都會受益于我在以后的學(xué)習(xí)、工作和生活中。在設(shè)計的過程中發(fā)現(xiàn)了自己的不足之處，對以前所學(xué)過的知識理

9、解得不夠深刻，掌握得不夠牢固。本次實驗我對一些基本操作有了更好的掌握，對于數(shù)字邏輯電路的設(shè)計也有了更深刻的理解。本次實驗老師都是要求獨立完成。在這一點上很好的鍛煉了我們的獨立完成設(shè)計的能力。這是一次有意義實驗。實驗過程中我們遇到了很多困難然后再自己的努力下克服困難，讓我們體會到的不僅是實驗課程設(shè)計的樂趣，更讓我們學(xué)會了怎樣面對困難。我想自己在計算機方面的知識還遠遠不夠，在今后的學(xué)習(xí)和生活中我會更加努力的不斷學(xué)習(xí)吸取新的知識，注重知識和實踐的結(jié)合。 最后，我們衷心的感謝課設(shè)期間一直指導(dǎo)和陪伴著我們的老師。五、附錄1.16選1選擇器源代碼：library ieee;use ieee.std_log
