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 using opt option and used ids/Weff. I have added the screenshot. Please help me to solve this problem.
