-The translation of a model described in Modelica to the corresponding model described as a hybrid DAE (see \cref{modelica-dae-representation}), involving expansion of inherited base classes, parameterization of base classes, local classes
-and components, and generation of connection equations from \lstinline!connect!-equations (basically, mapping the hierarchical structure of a model into a set of differential, algebraic and discrete equations together with the corresponding variable declarations and function definitions from the model).
