新手求助，encounter单元放置问题(已解决)

求助各位大大，从dc综合后输出的sdc文件在encounter里面放置标准单元时出现了这个问题，请问下怎么解决呢?另外encounter是否有像dc一样的error说明文件?

我的sdc文件开头是这些

这哪是sdc啊！

小编大大，那这是什么。dc出来的就是这个啊。

那叫sdf

这个是sdf，是延时信息，不是约束

恩，我弄错了。改过之后，貌似还是不行，出现这些。请问哪里还有问题呢?*** Starting placeDesign default flow ***

恩，是我的错误。多谢指点~

哪里不行?

标准单元好像还没有加进去。

用GUI确认标准单元是否加进去

没有，GUI看不到变化。

/usr/synopsys/10.9.1/linux/bin/mux.sdc
这个文件路径有意思
你都有下面的信息了，还说没有放进去?

从他一开始的问题就知道，在初学者身上，什么都有可能发生，估计他是GUI的view没有选对

抱歉啊 [img]file:///C:\Users\Administrator\AppData\Roaming\Tencent\Users\260523658\QQ\WinTemp\RichOle\X2}[TR8G(S97FI`3FLFB{G6.jpg[/img]我才学习使用encounter的。按照流程范例做，确实到了这部就走不下去了。

果然是，谢谢小编！

我的也加不进去，
