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-NIOSIIEDA/SOPC系统开发平台

2、软件：

QUARTUSII、SOPCBuilder、NIOSIIIDE

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后，恢复初始状态。

四、设计步骤

1、使用QuartusII建立一个工程文件和顶层文件；

2、使用SOPCBuilder建立一个简单NiosII硬件系统

1）启动SOPCBuilder

2）指定目标FPGA

3）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key

C、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A

E、添加一个3位的输出型PIO作为数码管的位选sel

F、添加一个8位的输出型PIO作为数码管的段选dat

4）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

SOPCBuilder行程图如下：

3、在QuartusII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Creatsymbol，生成Projectsing

4、在QuartusII中编译NiosII硬件系统并生成配置文件

1）在QuartusII加入NiosII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NiosIIIDE中建立C/C++工程，编写用户程序

6、编译用户程序

7、下载.SOF至FPGA,运行程序，观察结果

五、设计程序

六、设计结果

按键未按下时，处于初始状态：

LED1亮，LED2灭，数码管显示为0,蜂鸣器未启动；按键按下之后，LED1灭，LED2闪烁，数码管进入9秒倒计时并且蜂鸣器响；9秒后恢复初始状态。

七、设计问题

设计中遇到了不少问题：

一开始因为延迟原因使得蜂鸣器音乐间断，后来将延迟时间缩短后问题解决；

然后在数码管动态显示时，也存在延时问题，按下按键后数码管在一秒后才进入倒计时，修改程序后问题解决；

八、心得感受

通过本次设计，我们更加熟悉C语言和SOPC，也在自己动手设计中发现了平时所没遇到的很多问题，包括硬件和软件方面的，有一部分是粗心，有一部分确实是不够了解这门技术；因此在设计过程中，我们不断和其他小伙伴探讨后解决了问题，并从他们那里学到了不少东西。
