Set compatibility mode to PSA in PySpice

[direslimer]

Hello everyone,

I'm quite new to PySpice and ngSpice and I'm running into a problem I don't seem to find a solution for in the PySpice documentation.
I want to include a subcircuit of a MOSFET provided by the manufacturer into a PySpice simulation.
I'm always getting Error: 0, -0.5 out of range for pwr errors and gmin stepping is increasing until the iteration limit is reached.
If I am comparing the netlist of the LTSpice model (which is working) and the netlist in PySpice they are identical.

So I ran the netlist in ngSpice directly and if I'm not setting any compatibility mode, I'm getting the same errors as with PySpice.
But by using "set ngbehavior=psa" in a separate .spiceinit file for PSPICE mode, the model is running just fine.

My question is now, how can I set or replicate PSA Mode in PySpice?

I'm happy about any help.
Thank you all very much in advance.

Best regards,
Sven
