“…They tried the verification of the accessibility and the security of the Real-Time Systems. In (Fischer & Conard, 2000), the authors showed how the semantic relationship of approaches using Timing diagram can be combined and gave a seamless integration of hardware design and software development providing a common semantic basis for verification. In (Schlör, 2001), the authors derived the symbolic timed automata from the symbolic TD to formally describe the reactive systems and integration into verification framework.…”

Unified Modeling Language (UML) is using in the design notation in industry and academia projects. Interesting by the critical Real-Time System verification, it is important to ensure its dependability in order to avoid eventual errors. In this paper, the authors aim to extend the UML diagrams by adding a formal verification stage. They tackle with the UML2 timing diagram (TD), as interaction diagram in order to describe the system's behavior in temporal way. For that, the authors give a formal description for TD using Time Petri Nets (TPN). Then, they propose a formal verification by means of Romeo Model Checker. In particular, they show how to formulate quantitative properties using TCTL (timed computation tree logic). In addition, the authors show how they can derive the TCTL formulae from Object Constraint Language-Real Time (OCLRT) constraints. Finally, they illustrate the proposed approach through a real case study.
