Compositional Transformation of Message Sequence Charts into High-level Petri Boxes Daniel Gurovic und Wolfgang Fengler Department of Computer Science and automation University of Ilmenau, Germany Abstract The concern of this paper consist in utilizing the theoretical findings on the field of formal compositional semantics, in particular those of high level Petri nets, for the specification of communicating embedded systems. Transformation of these approaches and their evaluation in practice occurs with the aid of one of the formal rotation of the UML namely the Message Sequence Charts, particularly the MSC'96. Communication requirements of embedded systems are graphically specified and then transformed into an executable class of high level Petri nets.
