Software architecture description languages allow software designers to focus on high level aspects of an application by abstracting from details. In general, a system’s architecture is specified in a hierarchical way. In fact, hierarchical components hide, at each level, the complexity of the sub-entities composing the system. As rewriting logic is a natural semantic framework for representing concurrency,...
UML and MARTE are standardized modeling languages widely used in industry for the design of realtime systems. However, formal verification at early phases of the system lifecycle for UML/MARTE models remains an open issue mainly for dependability features. In this paper, we show how we can provide a formal verification of time properties from a UML/MARTE description. For this, we translate this latter...
Unified Modeling Language (UML) is a graphical modeling language based on diagrams is widely used both in industry and academia although its semantics is yet informal. In this work, we aim to give a formal semantics description of Interaction Overview Diagram (IOD) semantics. IOD as new diagram introduced by UML2 allows a hierarchical specification of system's behavior at more than one level. We establish...
