The ability to simulate GaN devices without practically using them is an extremely important step in the design process. For more detailed electrical simulations, EPC utilizes a hybrid of physics-based and phenomenological functions to achieve a compact spice model with acceptable simulation and convergence characteristics, including temperature effects for conductivity and threshold parameters. These can be found on the EPC Device Models page, while the Circuit Simulation Using EPC Device Models provides an in-depth look at these models. Supported model formats include P-SPICE, LTSPICE, TSPICE, SIMPLIS/SIMetrix, and Spectre. Also included on the Models page are STEP, Thermal Models, and the EPC Altium Library.

The GaN FET Thermal Calculator allows the optimization of the thermal solution once the losses have been determined.
