How to add these components on LTspice for simulation

[drakejest]

I would like to add these spice models so i can simulate them in LTspice.

    PBSS4350X (.txt)
    PBSS5350X (.txt)
    AO4407A (.mod)

I have looked into on how to add the models, but when I opened the library which contains all models, it looks different on the text files. The PBSS has a .SUBCKT and a .MODEL Diode on them. Do I have to add them to the diode file too?

The .mod file is even much more confusing, the files contains an NMOS where the mosfet where it came from is a PMOS.

My question is how do i add these files in proteus so i can simulate them?



It may be of note that doing method 1 in the turtorial where the spice text is just place on the drawing area results in an error.
