TI AMC1200 PSPICE file incompatibility with KiCad

Schematic Simulation (Ngspice)

I have downloaded the PSPICE file for the AMC1200 from the TI website. I get the following error message when I try to use it with KiCad 8.0.8

Please will you assist.

Note: Compatibility modes selected: ps lt a
Circuit: KiCad schematic

Thank You

There are no error messages, but some warning messages.

The ngspice MOS model does not support the RDS parameter. Typically this is not a critical issue.

I might consider adding it to ngspice, as it is available in PSPICE as well.

Thank you for your prompt response. I have it working and the results are what I expect so it isn’t affecting my design. I was just concerned in case I was missing something.
