DEVS is a well-established M&S framework. Through the history of its development, two main strands stoud out clearly: the so-called Classic DEVS and Parallel DEVS. Today, there is a need for DEVS modelers to deal with a unified formalism, as well as with a powerfull and yet intuitive formalism. This paper is a contribution to these needs. Three aspects are considered: (1) the strong link between the output and the internal transition functions and its impact on the modeling effort, (2) the coupling issue and its implicit impact on the transitions collision problem that has led to classic DEVS and parallel DEVS and, (3) the way to provide a unified specification framework.
