Broadband TCAD mixed-mode simulation framework for predictive modeling of fast dynamic switching events

In this paper, we develop a simulation framework for analyzing and optimizing the large signal, dynamic switching behavior of power devices. This framework enables us to use TCAD models of our active devices, together with a broadband description of the application board. All elements are coupled through a mixed-mode SPICE instance. Simulated results, obtained with this new method for two application boards, are compared to measurement data and their agreement is analyzed.
