进入ADE XL建立adexl设计文件后，先进行Nominal Corner 仿真，可以完成。如图所示：

但是，增加Corner －－ C0，ff工艺，温度－40、25、100，工艺角设计如图所示：

再进行仿真，就进行不下去，始终是pending状态

log提示信息如下：

原因3中提到的脚本确实不存在。请问有经验的朋友，这是什么原因引起的？如何解决？谢谢！

Corner设置里的模型文件和Test里面是分开的。你在Corner设置里面给出了了模型文件，但是对应的section没有给出。你打开Test里面的model setup，对照着把section都选好，记得选中激活再试试。

上面是根据我较早之前做仿真的经验得到的结论。我刚刚在ICADV20.1和spectre21.10下面试了一下，在这个版本下面，Corner里面没有设置Section的，都会从Test中获得。比较稳妥的检查方法是，打开input.scs文件。看看里面对应的模型文件有没有Section。打开input.scs所在文件夹，可以通过鼠标右击结果页面中的仿真结果所在列的任意单元格。然后在弹出菜单中选择Open Terminal，在打开的终端中进入子文件夹netlist。其中就可以看到input.scs文件了。
如果该文件中内容是正确的。可以在netlist文件中执行runSimulation文件。它会在命令行启动ADEXL GUI所设置的仿真。如果该仿真能顺利运行。那么可能就是Job Policy设置的问题了。这个就需要联系IT了。看log，很有可能是这个。不过还是先把Corner设置中的section可能存在的问题排除一下。
