版图大写，电路小写，改下大小写设置

飞翔的鸟 · 发表于 2024-11-5 08:53:17

en.....这么多bad component subtype，器件提取期间就出了错误了，感觉不是大小写问题

不谓侠 · 发表于 2024-11-5 09:03:26

衬底不对哇，看看是不是漏了层次

Wesevan · 发表于 2024-11-5 09:04:12

看着连线都没连完，先检查bulk电位有没有接上吧，都接上了就检查一下不同类型器件放在一块了导致器件识别不对，

单车镜头毁三代 · 发表于 2024-11-5 10:43:15

bad component subtype感觉是识别层出了问题，看看是不是layermap没加

110006 · 发表于 2024-11-5 11:36:48

看起来是器件名字大小写的问题，可以检查一下网表提取的subckt文档

我是噪声 · 发表于 2024-11-5 15:00:13

推荐发下LVS里提示错误的相关器件版图和电路图，还有ring和剖面图的相关信息

发散性思维 · 发表于 2024-11-8 16:20:30

大小写问题建议在rule找到 layout/schematic case
