Hi,

I want to use the commands LX18(), LX19(), and LX20().

But when I include bsimcmg.va, I will need to call the FinFET as X1 not M1.

And it seems that LX18(), LX19(), and LX20() can only use M1, e.g. LX18(M1).

So now I cannot run C-V simulation with BSIM CMG included.

LX18(X1) seems not to be a valid syntax.

Or is there any method that can use M1 but still including BSIM CMG and modelcard? Thanks!
==========================
Following is my code :

.hdl "bsimcmg.va"
.include "modelcard.nmos14"
...
vgs gate 0 dc=0
X1 gnd gate gnd gnd nmos14

.dc vgs -1 1 0.1
.print Cgg=par("LX18(X1)")
