remcirc solved the issue, thanks.
sharedspice - gradual slowdown of ngSpice_Command() despite using destroy all
Documentation says JFET2 supports AFAC parameter but it is not in source code
pdf VDMOS params table is cut off
I see the vector in "Initial transient solution" but linearize don't see such vector
Let's measure RMS value of 10V sinewave: * this prints 7.07 rms value VU1 1 0 DC 0 AC 1 0 SIN (0 10 200 0 0 0) .control tran 10u 20m 0 meas tran rms v(1) from=0 to=20m .endc .end Meas shows 7.07, when I print tran values and calculate RMS myself I get 7.05, ok, close enough. But when I use larger tran step, e.g. 50u, the accurracy goes down and I calculate RMS value 7.00, but the meas command still prints 7.07: * this also prints 7.07 rms value even tho step is larger VU1 1 0 DC 0 AC 1 0 SIN (0 10...
It is caused by having "VDMOS" in the model name, if I change it to QMY_VDMO it works.
If I add VDMOS model "source file.cir" freezes.
