Realizability and Verification of MSC Graphs
Scenario-based specifications such as message sequence charts (MSC) offer an intuitive and visual way to describe design requirements. MSC-graphs allow convenient expression of multiple scenarios, and can be viewed as an early model of the system that can be subjected to a variety of analyses. Problems such as LTL model checking are undecidable for MSC-graphs in general, but are known to be dec...

Scenario-based speciications such as message sequence charts (MSC) ooer an intuitive and visual way of describing design requirements. MSC-graphs allow convenient expression of multiple scenarios, and can be viewed as an early model of the system that can be subjected to a variety of analyses. Problems such as LTL model checking are known to be decidable for the class of bounded MSC-graphs. Our...
متن کاملRealizability of Dynamic MSC Languages
We introduce dynamic communicating automata (DCA), an extension of communicating finite-state machines that allows for dynamic creation of processes. Their behavior can be described as sets of message sequence charts (MSCs). We consider the realizability problem for DCA: given a dynamic MSC grammar (a high-level MSC specification), is there a DCA defining the same set of MSCs? We show that this...
متن کاملRealizability Criteria for Compositional MSC
Synthesizing a proper implementation for a scenario-based specification is often impossible, due to the distributed nature of implementations. To be able to detect problematic specifications, realizability criteria have been identified, such as non-local choice. In this work we develop a formal framework to study realizability of compositional MSC [GMP03]. We use it to derive a complete classif...
متن کاملRealizability of Graphs and Linkages
We show that deciding whether a graph with given edge lengths can be realized by a straight-line drawing has the same complexity as deciding the truth of sentences in the existential theory of the real numbers, ETR; we introduce the class ∃R that captures the computational complexity of ETR and many other problems. The graph realizability problem remains ∃R-complete if all edges have unit lengt...
