TSMC .18um工艺mos管总栅宽改了仿真结果不变

ic 617环境下，TSMC .18um工艺下总栅宽并不会随着finger number和width的变化而变化，如果手动改total width的话仿真结果跟没改是一样的，也就是说mos'管栅宽最大只有8um，不知坛友是否也有遇到上述情况的?能否给小弟支支招?

增加M不就增大栅宽了?

谢谢回复，增大m也没有，跟没增大之前一样的

增大之前仿真你看了什么参数?没有变化?怎么可能

电流电压，改了和没改一模一样

把finger设成10试试看呢

可能是工艺库没有装全?比如说skill文件丢失?

这是我在tsmc .18工艺库安装文件夹下搜skill文件的结果，也不知道缺不缺文件，能麻烦帮忙看一下吗?

是其他管子都这样还是就你这个管子这样?你这个管子怎么看着像是个电容?

libPath = strcat( libPath "/../skill")
会不会是你的skill文件夹没有?看目录是与PDK的文件夹相同目录。

试着用总线的形式来表示

所有的MOS管都这样，这个管子是二极管连接的MOS，因为选中了所以看起来有点像电容

我以前碰到过改w无效的问题，不过不是.18工艺
问题出在我同时include了两个pdk，我把另一个pdk注释掉就ok了
不太清楚你是不是同样的问题

多谢帮忙，我现在弄好了，原来是我没有把TSMC.18库的models和skill文件夹放到自己的工作库里，把着两个文件夹放进去就好了
