Then, a new method testing the double fault of combinational circuits based upon Boolean partial derivative is proposed.

在此基础上提出了基于布尔偏导数的组合电路双故障检测的新方法。

Analysis shows that the control core has a feature very similar to FSE (Fail Security) for a single fault or some sequent double faults.

分析表明，双微机核对于单故障和一类有序双故障具有非常类似于FSE(故障保险)的特征。

Fault links are indicated by a double line in an alternate color from normal links.

错误链接采用不同于正常链接的颜色显示的双线来指示。

Fault links are supported as well, shown with double-lines in a different color.

还支持采用不同颜色的双线显示的错误链接。
