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
