How to add the .net file provided by EPC for simulation

KW202603107421

When simulating the LMG1210, I want to use real GaN switches in the simulation. However, for models like the EPC2204, the manufacturer only provides a .net file. After changing the file extension to .lib, capitalizing .subckt and .ends, and appending EPC2204A, the simulation model still cannot be read.

    EPC GaN models often have more than the standard 3 pins (G, D, S). They usually separate the temperature sensor pins or substrate pins.

    Open the .lib file with Notepad.

    Find the line .SUBCKT. Count how many connections are listed after the component name.

    Solution: You need to create a new Symbol (.asy in LTspice) with the number and order of pins exactly matching the list in the .lib file. If you use the default nmos symbol (only 3 pins), the simulator will report an error due to missing connections.
