hello. I am trying to simulate the TPS55340 in the kicad spice but I encounter some error after I set the IC for the component
the error:

Based on the information given above, it is absolutely not possible to provide any support.

Basic info needed: KiCad version, operating system, ngspice version. Post the KiCad version info here.

Please also zip your project and post it here, including all model files used.

I am using KCad 9 on Mac 15.4 (24E248) I am not sure on the version of ngspice but I guess that it the version that coms with kicad9. the forum won’t let me upload the files is there other way that I can send you the files?
