encounter gds倒入virtuoso时standard cell位置正常，但是 metal层的位置却乱了

cwg540

我先用encounter导出gds文件，再将encounter 的gds文件和map文件用virtuoso stream in时standard cell位置正常，但是 metal层的位置却乱了（与encounter里的位置不一样）。
我就纳闷了，都是cadence的工具怎么还会出现这种问题。网上有的人说要对从encounter里导出的map对照着（encounter所用的lef文件和virtuoso所用的tf文件）进行相应的修改。

请问同仁们这个方法可行吗？可行的话怎么修改encounter里导出的map？

下面是我的stream in时出现的warning和我从encounter 里导出的map文件:

我刚刚查看了tf文件里好像有 ( M1                        61         M1           )

  ( M4                        64         M4           )

  ( M6                        66         M6           )
map里有

是不是应该把“METAL1  NET  1  0” 改成“M1 NET 61 0"
那map 文件里 "METAL1    SPNET        2      0"
和“METAL2  PIN  18  0” 应该怎么改呢？

lztogether

你的standard cell 在导入到virtusouo中 能看到吗？

darkoflight

map文件的左侧部分的名称必须要和你的tf文件相对应右侧部分应该和gds文件中的层次相对应

damonzhao

map有问题，要改成和技术库里面提供的layer的gds no.一致

williamloo

楼上正解。建议自己画几个方块，导出导入一下，重点注意导出的层号和map文件里面的层号。
