如果是插入buffer解决我感觉不现实，是不是我哪里综合出错了，spef是calibre提的，工艺库不支持wire——lode model.
或者是我应该怎么改，多谢了

这个是setup report啊。

您好！
我发现是calibre到处spef我好想做错了，我的做法是昨晚drc和lvs之后用pex提取门级网标，里面hcell用作了，但是也没找到，我查到lvs好像可以生产hcell,但是具体的命令没查到，您能给我说一下么，谢谢

没试过这个功能，帮不了你。

好的，我也试过用starrc提过参数，lef/def的时候缺map文件，这个提供的是给milkyway使用的，我想用milkyway提参数，又不知道什么是milkyway 的database是什么。您知道么

milkyway database 是ICC的PR数据

d多谢您的回答。我已经感觉很无力了，calire提取文件加载xcell之后，提出的spef文件里面仍有管子，而且文件里面都是序号，没有名字，也不知道哪里设置错了数字水好深

没有用calibre抽spef，不过感觉你抽取的spef是transistor level的，你试试看有没有option设置是gate level的。找calibre manual看看。

我选的是gate level ，也加了xcell但是不对，~

我准备放弃calibre用starrc了，问题是starerc没提供lef/def的map文件，只提供了给milkyway的map.要写的话我不知道格式，您知道相关的格式或者例子么
