Recently, modeling has received a lot of attention in the design of embedded computing systems. StateCharts is one of the modeling specifications, which has been successfully implemented in a commercially available tool suite. We argue that the DEVS formalism is more expressive than StateCharts and can also be applied to the design of such systems.In this paper we want to show that we can in fact build equivalent StateChart models directly from DEVS models and execute them in the available development environments. The presented mapping of the two system modeling formalisms promises to combine the benefits of formally well-defined models and a sound tool implementation.
