數(shù)字電路與邏輯設(shè)計(jì)實(shí)驗(yàn)報(bào)告-王云深

1、 數(shù)字電路與邏輯設(shè)計(jì)實(shí)驗(yàn)-4位簡易密碼鎖 姓名：王云深學(xué)號(hào)：10210889班級(jí)：2011211209軟件簡介：Quartus II 是Altera公司的綜合性PLD/FPGA開發(fā)軟件，支持原理圖、VHDL、VerilogHDL以及AHDL（Altera Hardware Description Language）等多種設(shè)計(jì)輸入形式，內(nèi)嵌自有的綜合器以及仿真器，可以完成從設(shè)計(jì)輸入到硬件配置的完整PLD設(shè)計(jì)流程。Quartus II可以在XP、Linux以及Unix上使用，除了可以使用Tcl腳本完成設(shè)計(jì)流程外，提供了完善的用戶圖形界面設(shè)計(jì)方式。具有運(yùn)行速度快，界面統(tǒng)一，功能集中，易學(xué)易用等特點(diǎn)。

2、Quartus II支持Altera的IP核，包含了LPM/MegaFunction宏功能模塊庫，使用戶可以充分利用成熟的模塊，簡化了設(shè)計(jì)的復(fù)雜性、加快了設(shè)計(jì)速度。對(duì)第三方EDA工具的良好支持也使用戶可以在設(shè)計(jì)流程的各個(gè)階段使用熟悉的第三方EDA工具。此外，Quartus II 通過和DSP Builder工具與Matlab/Simulink相結(jié)合，可以方便地實(shí)現(xiàn)各種DSP應(yīng)用系統(tǒng)；支持Altera的片上可編程系統(tǒng)（SOPC）開發(fā)，集系統(tǒng)級(jí)設(shè)計(jì)、嵌入式軟件開發(fā)、可編程邏輯設(shè)計(jì)于一體，是一種綜合性的開發(fā)平臺(tái)。Maxplus II 作為Altera的上一代PLD設(shè)計(jì)軟件，由于其出色的易用性而得到了

3、廣泛的應(yīng)用。目前Altera已經(jīng)停止了對(duì)Maxplus II 的更新支持，Quartus II 與之相比不僅僅是支持器件類型的豐富和圖形界面的改變。Altera在Quartus II 中包含了許多諸如SignalTap II、Chip Editor和RTL Viewer的設(shè)計(jì)輔助工具，集成了SOPC和HardCopy設(shè)計(jì)流程，并且繼承了Maxplus II 友好的圖形界面及簡便的使用方法。實(shí)驗(yàn)?zāi)康模?設(shè)計(jì)并實(shí)現(xiàn)一個(gè)數(shù)字密碼鎖，密碼鎖有四位數(shù)字密碼和一個(gè)確認(rèn)開鎖按鍵，密碼輸入正確，密碼鎖打開，密碼輸入錯(cuò)誤進(jìn)行警示。實(shí)驗(yàn)要求：基本要求：1、密碼設(shè)置：通過鍵盤進(jìn)行4 位數(shù)字密碼設(shè)定輸入,在數(shù)碼管上顯

4、示所輸入數(shù)字。通過密碼設(shè)置確定鍵（BTN 鍵）進(jìn)行鎖定。2、開鎖：在閉鎖狀態(tài)下，可以輸入密碼開鎖，且每輸入一位密碼，在數(shù)碼管上顯示“-”，提示已輸入密碼的位數(shù)。輸入四位核對(duì)密碼后，按“開鎖”鍵，若密碼正確則系統(tǒng)開鎖，若密碼錯(cuò)誤系統(tǒng)仍然處于閉鎖狀態(tài)，并用蜂鳴器或led 閃爍報(bào)警。3、在開鎖狀態(tài)下，可以通過密碼復(fù)位鍵（BTN 鍵）來清除密碼，恢復(fù)初始密碼“0000”。閉鎖狀態(tài)下不能清除密碼。4、 用點(diǎn)陣顯示開鎖和閉鎖狀態(tài)。提高要求：1、輸入密碼數(shù)字由右向左依次顯示，即：每輸入一數(shù)字顯示在最右邊的數(shù)碼管上,同時(shí)將先前輸入的所有數(shù)字向左移動(dòng)一位。2、 密碼鎖的密碼位數(shù)（46 位）可調(diào)。3、自擬其它功能
