SOPC课程设计实验报告

1、精选优质文档-倾情为你奉上SOPC课程设计实验报告 基于SOPC的警示灯设计 2013电子信息工程3班李婕 罗丹妮一、 设计目的 1、 熟悉掌握SOPC的基本流程2、 设计一个警示灯并满足基本要求3、 通过设计发现问题并解决二、 设计设备1、硬件：PC机、SOPC-NIOS II EDA/SOPC系统开发平台2、软件：QUARTUS II、SOPC Builder、NIOS II IDE三、 设计内容 初始状态为红灯（LED2）熄灭，绿灯（LED1）点亮，数码管显示为0。 当按键按下，红灯（LED2）闪烁，绿灯（LED1）熄灭，同时蜂鸣器响起，数码管开始倒计时9S，此状态持续时间为9s。 9s

2、后，恢复初始状态。四、 设计步骤1、 使用Quartus II建立一个工程文件和顶层文件；2、 使用SOPC Builder建立一个简单Nios II硬件系统1） 启动SOPC Builder2） 指定目标FPGA3） 添加NiosII内核及其他外设A、添加NiosII、SRAM、JTAG-UART、Avalon总线的IP核 B、添加一个2位的输入型PIO作为按键keyC、添加两个1位的输出型PIO作为 led1及led2的输出端口D、添加一个1位的输出型PIO作为蜂鸣器的输入端口AE、添加一个3位的输出型PIO作为数码管的位选selF、添加一个8位的输出型PIO作为数码管的段选dat 4）

3、指定基地址和中断优先级 5） 设置NiosII复位和异常地址6) 编译生成NiosII系统SOPC Builder行程图如下：3、在Quartus II中建立一个蜂鸣器 1） 用VHDL语言编写蜂鸣器程序 2） 编译成功后Creat symbol，生成Project sing4、在Quartus II中编译Nios II硬件系统并生成配置文件 1） 在Quartus II加入Nios II系统符号到顶层文件 2） 给各端口加入输入输出引脚，并重命名 3） 设置参数 4） 编译顶层文件 5） 分配管脚 6） 再次编译5、在Nios II IDE中建立C/C+工程，编写用户程序6、编译用户程序7、
