Abstract
Using UML or SysML models in a verification-centric method requires a property expression language, a formal semantics, and a tool. The paper introduces TEPE, a graphical TEmporal Property Expression language based on SysML parametric diagrams. TEPE enriches the expressiveness of other common property languages in particular with the notion of physical time and unordered signal reception. TEPE is further instantiated in the AVATAR real-time UML profile. TTool, an open-source toolkit, implements a press-button approach for the formal verification of AVATAR-TEPE properties with UPPAAL. An elevator system serves as example

Model-driven engineering with domain-specific meta-modelling languages
Domain-specific modelling languages are normally defined through general-purpose meta-modelling languages like the MOF. While this is satisfactory for many model-driven engineering (MDE) projects, several researchers have identified the need for domain-...

ICECCS '08: Proceedings of the 13th IEEE International Conference on on Engineering of Complex Computer SystemsThe UML is now the most widespread language for systems modeling. However, this language has been designed as a general purpose modeling language that may lack for modeling constructs for specific domain, as for the real-time embedded (RTE) domain. In ...
