Fatal error: No such subcircuit: S5_120_FA_VAR (Infineon MOSFET level 1 model)

QSPICE
1

Hello,

I am trying to use a level 1 infineon MOSFET in my simulation. In the spice model it makes a reference to another subckt S5_120_FA_VAR. As suggested in a previous post, I have marked the tick box ‘Include entire file’ as shown. However I still get the fatal error above. It seems to still be missing the S5_120_FA_VAR subckt.

Is anyone able to support with this?

Much Appreciated

In “Choose a Subcircuit,” you should select your device instead of a subcircuit of it. Therefore, choose “IAUTN12S5N018T.” You are correct that the “Include Entire File” option needs to be selected.

Thanks for the prompt response much appreciated. I actually select the “IAUTN12S5N018T” and then create the model. But when I run I get the error that there is no subcircuit S5_120_FA_VAR.

It seems Include Entire File only can include .subckt after “Choose a Subcircuit” in its netlist library. Infineons library put the common .subckt at beginning, and this seems ignored by Qspice as IAUTN12S5N018T is after that.

Here I put dependent subckt to bottom.
