Hi everyone,
I am trying to plot current density (Id/Weff) v/s Vgs i.e Vgs sweep, but unable to plot and get following error in CIW (IC616 virtuoso):-
expression evaluation fAIled: val is not legal.
expression evaluation failed: OPT("/M0","ids")/OPT("/M0","weff")
"("quotient" 0 t nil ("*Error* quotient: can't handle (srrWave:0x23af1020 / nil)"))"
I tried to make expression in calculator usingopt option and used ids/Weff. I have added the screenshot. Please help me to solve this problem.

为何都喜欢用Ubuntu呢

从出错信息上看, 分母上的波形不存在啊, 所以不能作除法.
在sweep分析中，OP函数返回的是单一数值，你的用户函数需要从sweep分析产生的结果中构建，不能从OP函数构建。
thank you @amodaman. So do i need to declare width as variable and sweep it?
