On the SPICE OPUS website [ http://www.spiceopus.si/release.html ], it
looks like the syntax is:
[[c[apacitance]=]{[<value>] [<expression>]}]}
Have you tried just using the value for cj? For example:
cj={0.2m}
It look like it might not like the "f/m^2" [units of capacitance (Farad)
per area (meters^2)] in cj:
cj={.2mf/m^2}

Hi!
I'm designing my final project for my Electrical Engineering
Bachelors degree and I decided to use electric to design my
circuits. The only problem is I can't get the spice models to work
at all! It seems there is a problem with the transistors models,
but I just can't figure out what it is.
The error I get is the following:
Warning: nomod not yet implemented - ignored.
Warning: limpts not yet implemented - ignored.
Warning: itl5 not yet implemented - ignored.
Warning: lvlcod not yet implemented - ignored.
Error: m: no such vector.
Arithmetic substitution in:
.model n nmos level=1 kp=60e-6 vto=0.7 gamma=0.3 lambda=0.05
phi=0.6 ld=0.4e-6 tox=40e-9 cgso=2.0e-10 cgdo=2.0e-10 cj={.2mf/m^2}
at expression no. 1 failed. Reason:
failed to parse the expression
Module: top level circuit
.model n nmos level=1 kp=60e-6 vto=0.7 gamma=0.3 lambda=0.05
phi=0.6 ld=0.4e-6 tox=40e-9 cgso=2.0e-10 cgdo=2.0e-10 cj={.2mf/m^2}
arithmetic substitution failed
in file testInverter.spi on line 11
Error encountered while parsing the circuit.
Starting .control block in spite of errors.
From what I could gather, the variable m is necessary to define
the trainsistor, and yet it is nowhere to be found.
Is there anyone that can help me with that?
