Modeling and simulation have been established as fundamental facilities in the development of analog and analog-digital systems. Essential advances have been achieved by the usage of behavioral modeling languages. These languages can be considered as a link between the technical problem and the mathematical model that can be evaluated by computational methods. The paper outlines the various possibilities that are offered by the language VHDLAMS – standardized by the IEEE to describe analog and mixed-signal systems – and the language Modelica. The underlying modeling approaches are compared. Last but not least; the potential to transform models written in one language into models of the other language is discussed.
