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?

@User: 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?

@User: They should be included with the usual

.lib sky130.lib.spice

.

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?

@User 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!
