SOPC課程設(shè)計實(shí)驗報告

1、精選優(yōu)質(zhì)文檔-傾情為你奉上SOPC課程設(shè)計實(shí)驗報告 基于SOPC的警示燈設(shè)計 2013電子信息工程3班李婕 羅丹妮一、 設(shè)計目的 1、 熟悉掌握SOPC的基本流程2、 設(shè)計一個警示燈并滿足基本要求3、 通過設(shè)計發(fā)現(xiàn)問題并解決二、 設(shè)計設(shè)備1、硬件：PC機(jī)、SOPC-NIOS II EDA/SOPC系統(tǒng)開發(fā)平臺2、軟件：QUARTUS II、SOPC Builder、NIOS II IDE三、 設(shè)計內(nèi)容 初始狀態(tài)為紅燈（LED2）熄滅，綠燈（LED1）點(diǎn)亮，數(shù)碼管顯示為0。 當(dāng)按鍵按下，紅燈（LED2）閃爍，綠燈（LED1）熄滅，同時蜂鳴器響起，數(shù)碼管開始倒計時9S，此狀態(tài)持續(xù)時間為9s。 9s

2、后，恢復(fù)初始狀態(tài)。四、 設(shè)計步驟1、 使用Quartus II建立一個工程文件和頂層文件；2、 使用SOPC Builder建立一個簡單Nios II硬件系統(tǒng)1） 啟動SOPC Builder2） 指定目標(biāo)FPGA3） 添加NiosII內(nèi)核及其他外設(shè)A、添加NiosII、SRAM、JTAG-UART、Avalon總線的IP核 B、添加一個2位的輸入型PIO作為按鍵keyC、添加兩個1位的輸出型PIO作為 led1及l(fā)ed2的輸出端口D、添加一個1位的輸出型PIO作為蜂鳴器的輸入端口AE、添加一個3位的輸出型PIO作為數(shù)碼管的位選selF、添加一個8位的輸出型PIO作為數(shù)碼管的段選dat 4）

3、指定基地址和中斷優(yōu)先級 5） 設(shè)置NiosII復(fù)位和異常地址6) 編譯生成NiosII系統(tǒng)SOPC Builder行程圖如下：3、在Quartus II中建立一個蜂鳴器 1） 用VHDL語言編寫蜂鳴器程序 2） 編譯成功后Creat symbol，生成Project sing4、在Quartus II中編譯Nios II硬件系統(tǒng)并生成配置文件 1） 在Quartus II加入Nios II系統(tǒng)符號到頂層文件 2） 給各端口加入輸入輸出引腳，并重命名 3） 設(shè)置參數(shù) 4） 編譯頂層文件 5） 分配管腳 6） 再次編譯5、在Nios II IDE中建立C/C+工程，編寫用戶程序6、編譯用戶程序7、
