Liberate使用问题

亭ting

在用Liberate对标准单元提取时序等信息时，出现了下面的错误提示，不知道大家又没见过。之前都没有出现过，寻求各位的帮助！

看着像是工具的环境变量问题

看着像是工具的环境变量问题

但是换成另外一个工艺，就没有问题了。难道是有些设置不适合在另一个工艺下，我再检查检查吧

仿真仿不了，很有可能是工艺的问题啊

一般来说这是随机错误，重跑就能过了。可是你用同样的设置还能重现的话，那就是工具版本或者设计的问题了。

因为设置了一个不属于这个工艺可用的变量。define_leafcell，这个没用对。

你好，我也遇到了这样的问题，请问最后是怎么解决的呢

你好，请问如何找工艺库的可用变量呢？
