在DC的时候定义了时钟，跑了icc之后得到sdc文件。用这个文件跑pt的时候一直报错说nothing_matched for clock_name。是因为我pt脚本中没有定义时钟吗？需要重新定义时钟吗？

你的sdc里不是应该有才对吗

读sdc文件时一直出错，要么就是找不到match的时钟要么就是找不到net。不知道为什么。

读入sdc出错的话，后面肯定会报错了，是什么错误，贴上来看看

都是类似于这样的错误

zhanggd · 发表于 2016-10-27 09:31:52

是不是没有把Verilog读进去？

杰克淡定 · 发表于 2016-10-27 09:35:03

DC定义的时钟是在综合网表上的，ICC之后这些cell或者net被优化掉或者改变了名字，所以报错。你去ICC后的网表里，看看能不能找到 U4IM/u1/add_309/n13即可证实

肯定读了，请问下pt如果出了很多setup时间的error该怎么改呀

[求助] 做pt的时候需要再次定义时钟吗？
