There is a homework; I solve the question and ı have to plot it by using Pspice A/D

The given parameters are;

NA = 10^15 cm-3 (Substrate Doping)
ND = 10^19 cm-3 (Source/Drain Doping)
NA(sw) = 10^18 cm-3 (Sidewall p+ Doping)
LM = 2 um (Mask Channel Length)
LD = 0.25 um (Gate Overlap)
W = 5 um (Channel Width)
Y = 10 um (Junction Length)
xj = 1 um (Junction Depth)
tox = 45 nm (Gate Oxide Thickness)
un = 500cm2/V-s (Surface Mobility)
VTO = 1V (Zero-Bias Threshold Voltage)
lambda =0.05 V-1 (Channel-Length Modulation)

and ı found csb cdb and cox ı wrote the code but there is an error as you see

VDS 1 0 dc 5V
VGS 2 0 dc 5V
M1 2 1 0 NMOD NMOS (Level=2 L=1.5U W=5U LD=0.25U AD=3E5 PD=5E-11)
--------------------$
ERROR -- unknown parameter

+PB=0.8188 CJSW=1.9435E-18)
.dc VDS 0 5 0.2 VGS 2 5 1

.END

I tried to fix it but ı could not please help me ı tried to fix it for 4 days.

 

anybody else?

 

Can you tell which parameter is unknown?
I guess reading the relevant parts of user´s guide and reference manual will answer most of your questions. My guess is that you are using a different level of nmos model, but I never really wrote any analog models, just digital ones.
