报错如下:  像是加的port没有连接到metal1，在after transformation后，net变多了。改如何设置呢？

看起來有可能像是 m1_text 沒貼在 metal1 上的情形

那label没对应到相应的层上啊

terry8876 · 发表于 2012-3-13 22:09:37

你再看看电路，顶层电路是几个pin，是什么名字你就用几个pin及对应的名字，不要把底层的pin打到顶层来。
比如你的INV输入输出为IN,OUT，但在顶层接的A,B。你若用Label把IN,OUT,A,B都打到顶层cell了的话LVS可能会报错。

就一个反相器，没有调用层。另外你们说的label是指打pin的时候写的名字吗？

DruculaC · 发表于 2012-3-15 12:58:12

回复 2# motofatfat

我把M1TXT画在M1上，calibre应该是自动认定这个pin链接到了M1上才对呀。。

回复 3# xycxyc1989

应该怎么对应呢？

motofatfat · 发表于 2012-3-15 17:25:05

選用 M1_TEXT layer
Create Lable
讓 + 落在 metal1 上

half_honey · 发表于 2012-3-16 08:39:39

回复 6# DruculaC

你的label是不是+没有在M1上？看M1TXT是对的啊

DruculaC · 发表于 2012-3-17 11:23:33

回复 8# motofatfat

恩，确实是这个问题，要让+落在M1上才行。。。
多谢大家了！！
