VHDL-AMS Electromagnetic Automatic Modeling for System Simulation and Design

To improve interoperability between system-level modeling and simulation, this paper proposes an approach to export models from dedicated magnetic tools into a standardized format, such as Very-high-speed integrated circuits Hardware Description Language-Analog and Mixed Signal (VHDL-AMS), as a powerful modeling language. The goal is to let designers use a unique modeling approach and single simulation tool to simulate the behavior of a complete electromagnetic system and to make the translation of existing models to VHDL-AMS easy. Thus they can reduce the investment. This paper addresses this methodology as a computer-aided generation of the VHDL-AMS code from macro and micro electromagnetic devices for system simulation. The translation uses model-driven engineering methods for the transformation of one model to another and the code generation from models. Implementation and methodology are illustrated on a dynamic E-shaped actuator as a macro-system case study and a diamagnetic levitation device as micro-system one.
