## 4.2运行指令测试程序
|
||||
## 4.2Linux平台环境搭建
|
||||
|
||||
### 4.2.1 运行旧的指令测试程序
|
||||
这里以Ubuntu系统为例进行说明。
|
||||
|
||||
1. 下载iverilog源码
|
||||
|
||||
`git clone https://github.com/steveicarus/iverilog.git`
|
||||
|
||||
2. 切换到v11分支(必须用V11或以上的版本)
|
||||
|
||||
`git checkout v11-branch`
|
||||
|
||||
3. 安装依赖
|
||||
|
||||
`sudo apt-get install autoconf gperf flex bison build-essential`
|
||||
|
||||
4. 编译、安装iverilog和vvp
|
||||
|
||||
```
|
||||
sh autoconf.sh
|
||||
./configure
|
||||
make
|
||||
make install
|
||||
```
|
||||
|
||||
5. 创建python软链接
|
||||
|
||||
`sudo ln -s /usr/bin/python3.8 /usr/bin/python`
|
||||
|
||||
其中/usr/bin/python3.8对应你实际安装的python版本。
|
||||
|
||||
6. 安装gtkwave
|
||||
|
||||
`sudo apt-get install gtkwave`
|
||||
|
||||
**注意:**如果使用其他版本的GNU工具链,可以自行修改tests/example/common.mk文件里的这几行内容:

## 4.3运行指令测试程序
|
||||
|
||||
这里以Windows平台为例进行说明,Linux平台是类似的。
|
||||
|
||||
### 4.3.1 运行旧的指令测试程序
|
||||
|
||||
旧的指令测试程序属于比较早的指令兼容性测试方法,虽然目前RISC-V官方已经不更新了,但仍然是一个比较好的测试参考。
