Abstract

The ever growing requirement for safety in embedded systems, together with the willingness of having a modelling language to describe both the physics and the software that controls it makes Modelica an interesting candidate to design, simulate and implement complex systems. Originally designed to address multi-physics, since its version 3.3 Modelica integrates constructions to describe discrete controllers. Now the question of using Modelica to design critical embedded software arises.

In this paper we address the problem of defining a practical Modelica subset that can be entirely formalized and we sketch the formalization of this subset with a concrete example. This work should serve as a basis to define a suitable language that can be used to both simulate systems and generate embedded critical code.
