KiCAD has no library system/structure for Spice models, and they are not stored with the project/schematic.
Users are left to themselves when storing simulation models.
A big help would be having a user environment variable pointing to the Spice models. Like the one I set up here:
It should be used in this window/context as “base folder” when clicking the folder icon for searching deeper for the actual model files:
This would allow efficient storage of models that can be found quickly by the user.
[STRIKE ]It would also eliminate a productivity-killing flaw (which ought to be fixed anyway) in KiCAD for Linux: the file dialogs do not show hidden files or directories (with preceding . ). No navigation is possible.
As the default KiCAD installation puts user libraries under
/home/$USER/.local/share/kicad/7.0/
that’s a major Duh! [/STRIKE]
Solved: accidentally right-clicking the title bar on the window allowed me to tick options, including hidden files.
Super-intuitive, after searching settings for hours…
