VHDL-AMS to support DAE-PDE coupling and multilevel modeling

摘要

With the increasingly high level of electrical system integration, the modeling of both the system behavior, and the detailed physics of its elements becomes necessary. VHDL-AMS language allows to describe a range of physical systems, such as electro-magnetic devices, using a unified design approach to simulate a complete system. In the paper, the behavioral modeling of multiple energy domains is achieved using VHDL-AMS. This illustrated how the interactions between domains take place with an electromagnetic actuator. Then, a multi-level hierarchical modeling methodology, using a V-shaped-based design approach, allows functional modeling, structural behavioral modeling and detailed component modeling.
