※ 引述《qoogood1234 (ZACH)》之铭言：
: 我是新手
: 不好意思
: 请问一下
: 要怎麽设定 mosfet 的 L W Vt VA Cox 等等参数
: 跟
: proterty edit 中的 kp VTO CGSO CGDO 等参数 有关系吗??
: 谢谢解答><
MOSFET's width and length can be written in the Circuit Description.
For example,
MOSFET's_name drain gate source body MOSFET's_model W=1.25u L=0.6u
It means that the width=1.25um and length=0.6um
Besides,Vt,VA and Cox
If you use Level 1, you should use the following equtions to tune the
parameters in the right hand.
VTH0 = VFB+PHI+K*(PHI)^(1/2)
Cox=CGDO/(0.6*XJ)
But if if you use Level 5 or higher,
you can input these parameters directly.

Above the all is for version 9.0.
For version 16.0, I did NOT have time to try them...
