I have been making schematics with general transistors with a pinout similar to the ones I plan on using. The transistors that I am using are not in the libraries or any of the libraries that I have found. I have other programs like LTspice and TinaSpice - what is the best and easiest way to assign the parameters and components names so that I can then run sims on the projects prior to etching a PCB?
Depending on your workflow - if you use the BOM capability you will need to modify the symbols in EEschema to have the correct information or make your own personal libraries and use those.
As for simulating in KiCAD… not my cup of tea.
