如何使用 Spin 从命令行检查 Promela 代码

How to use Spin to check Promela code from the command line

我正在寻找如何在 Windows 10 命令行上使用 Spin 分析 train.pml 的输出。

如能帮助文件正确输出,我们将不胜感激。

先决条件: 在 Windows 10 上获得带有 gcc 的工作环境(例如 参见these instructions) or, alternatively, get a virtual environment with some GNU/Linux distribution. Also, correctly install Spin在目标系统中。


只有两种可能的方法:

  • 选项A.:

    ~$ spin -a train.pml
    ~$ gcc pan.c -o verifier
    ~$ ./verifier -a -N c1
    ...
    ~$ ./verifier -a -N c8
    ...
    
  • 选项B.:

    ~$ spin -search -ltl c1 train.pml
    ...
    ~$ spin -search -ltl c8 train.pml
    ...
    

目前,属性 c1, c5, c7, c8 在您的模型上 已验证,而 c2, c3, c4, c6 未验证.还有一些关于 未达到的最终状态 的抱怨。请检查后一种情况是否不违反您系统的规范(这可能是问题也可能不是问题),并且验证结果是否符合您的预期。


作为参考,这是您在验证 属性 c1:

时应该获得的 正确输出 的示例
~$ spin -search -a -ltl c1 trail.pml
...
pan: ltl formula c1
