To improve interoperability between system level's modeling and simulation, this paper proposes an approach to export models from dedicated magnetic tools into a standardized format, such VHDL-AMS, as powerful modeling language. The goal is to let designers to use a unique modeling approach and single simulation tool to simulate the behavior of a complete electromagnetic system and to make easy the translation of existing models to VHDL-AMS. Thus preserving investment has been provided for them. The 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 (MDE) methods as the transformation of model to another and the code generation from models. Implementation and methodology are illustrated on a dynamic E-shaped actuator such a macro-system case study and a diamagnetic levitation device as micro-system one.
Lab-on-chips (LOCs) are small systems, which integrate, in the same device, several functions involving chemical analysis with bio-processing functionalities typically performed in a laboratory. As a consequence, it is a multi-domain system that can be described and designed with VHDL-AMS, a hardware description language that natively supports electronics, thermics and fluidics. On the other hand, the biological part of the LOC is often modeled and simulated with languages suitable to the field of biology. One of the most commonly used ones is SBML (System Biology Markup Language). To promote the integration of biological parts of the LOCs in the VHDL-AMS environment, we have developed software that automatically generates the VHDL-AMS models from SBML descriptions. The potential of this tool is illustrated in the context of the design of the lab-on-chip suitable for the detection of micro-pollutants in drinking water.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
