Why is Matlab unable to import Wolfspeed Mosfet with Diode Model?

Hi,

I'm trying to import Mosfet Model parameters from PLECS .xml file provided by Wolfspeed using ee_importDeviceParameters function, however, I keep getting this error:

I have already inserted a mosfet block in Simulink with the body diode included and I use the function like this.

ee_importDeviceParameters("E3M0040120J2.xml","wolfspeed","untitled/MOSFET (Ideal, Switching)", GateResistanceOn=1, GateResistanceOff=1)

Is there anything I am missing?

Thanks in advance!

It is not currently supported to automatically parameterize a MOSFET (or IGBT) with protection diode.

To parameterize an IGBT or MOSFET with a protection diode, model the diode externally. Call the ee_importDeviceParameters function twice; once to parameterize an IGBT (Ideal, Switching) or MOSFET (Ideal, Switching) block and once to parameterize a Diode block with corresponding xml files. This will not work if the package class is "MOSFET with Diode".

Thank you for your answer.

I think I also should mention that ee_importDeviceParameters also doesn't work with .xml models that includes lookup function for the formula.
