求助，starRC提的spef文件问题【已解决】

ICSYS

     想请教一下各位牛人，我用starRC抽取RC参数生成spef网表，目前网表里的问题是有ln_前缀的net名，导致后续Primetime无法读取文件做时序分析，造成的原因查询到时因为版图里的net没有通过LVS验证或者在nxf文件里没有该net,因此starrc会以ln_的形式表示出来（可是gds是通过了LVS验证的，没有问题。），想问一下怎么消掉这个ln_？谢谢。。

你starrc flow怎么用的， star.cmd帖出来看看， flow有问题

我是用lef/def flow提参数，提示这样的。。。

没看出什么致命问题，  couple_to_ground 应该选no吧，

pt啥error， 觉得还是网表，spef对不上，

   之前用CCI flow做的，问题很多，发现这个不行。换了提取流程。

======================================
提出来了。删掉多余金属层就行了。

用普通flow吧，CCI是给gds level用的，
