Do anyone know that the corner.rf file actually is? Is it a specific device corner for high-frequency models or another thing that shares the RF acronym?
And how can I invoke it inside xschem? :)

I don’t seem to have this file in my install. Where did you find it?

<@U02A4K5TG5B>:  There are RF corner models in open_pdks `$PDK_ROOT/sky130A/libs.tech/ngspice/corners/_corner/_rf.spice` where _`corner`_ is one of `tt`, `ff`, etc.  These models correspond to the RF device layouts in `sky130_fd_pr/gds/sky130_fd_pr.gds`.

Ok, great :)
And how does one use these models in xschem? Do I need to reference each cell separately or is there a .lib command I can use?

<@U02A4K5TG5B>:  They should be included with the usual `.lib sky130.lib.spice` .

To use them in xschem, you would need to make sure that the device name is the full device name of the RF component, e.g.,  `sky130_fd_pr__rf_nfet_01v8_bM02W1p65L0p15` .

I see, thank you for the information. So if I invoke the 4-terminal nmos symbol, I would need to change the 'model=' line and add the RF get model that I want to use?

<@U02A4K5TG5B> yes it should work. Enter the model attribute without the `sky130_fd_pr__` prefix, it will be added by xschem.

And so it did :)
Thank you all for the help, as always!
