Help Solving an Aim-Spice HFET Modeling Issue with VAX

[ArtemSH]

Good day!

Please help me with HFET model for Aim-Spice!

I have a problem with IV modeling...

VAX
vds 1 0
vids 1 100
A1 100 2 0 Mhemt l=0.3u w=150u
vgs 2 0
.MODEL Mhemt PHFET
+d1=0.03e-6
+delta=3
+deltad=4.5e-9
+di=0.01e-6
+epsi=1.0841e-10
+eta=1.4
+lambda=0.05
+m=3
+mu=0.4
+nmax=2e16
+rd=0
+rs=0
+sigma0=0.03
+vs=0.8e5
+vto=0.7

please find a mistake in listing...

p.s soory for my english

Welcome to the PF. What error are you getting? Is it a SPICE compiler error, or a behavioral anomoly?

As the DI value of current becomes smaller, this effect should not be. How can I make with a decrease in Di current value decreased?
