Electromagnetic Actuators are complex systems belonging different physical domains, which should have suitable representative model on each stage of the design cycle The classical validation of such systems by separate simulation o each element does not offer the possibility to predict the behavio of the whole system. To overcome such limitations, we propose unified architecture for the multi-level and multi-accurac modeling of electromagnetic devices. In the paper, VHDL-AM is used to support the dynamic behavioral and structura modeling of a multi-domain actuation system, and focuses on th multiple modeling of magnetic components for simulation an optimization studies and their integration into the V design cycle
