工艺库中没有这四个器件，在csc文件中搜索，在工艺角中加入dio_dnw

加入工艺角后直接爆炸，满屏error

萌新小白，不知道怎么操作。工艺库的csc文件是只读的，没法编译，是不是厂家写错了，前面应该加+号

模型文件的语法并没错，nch3_dnw模型里面包含了两个diode而已。关键是你引用model文件不完整，所以造成很多未定义的参数。打开晶圆厂给你的PDK文档，里面看一下说明就知道需要在ADE-L中设置什么模型文件名就好了。乳沟你把所有文件一股脑都加上，说不定还会有重复定义参数的错误冒出来，所以最好老老实实读一下文档。

应该是工艺角加错了，dio_dnw, mos这些工艺角不是直接给你用的，看看文件开头的注释，会告诉你加哪些工艺角。

我猜你工艺没装好，gf的工艺应该有完整的脚本支撑的，根本不需要你配置model file

服务器上装的，每次启动还要加pdk.csh,安装可能是有点问题，每次仿真都要选工艺角

按照工艺文件里面的安装文档重装吧，gf的脚本是非常完整的，基本上所有的东西都帮你配好了，不需要手动调用任何设置的。
