Real-time systems are becoming more complex andopen, thus increasing their development and verification costs.Although several static verification tools have been proposedover the last decades, they suffer from scalability and precisionproblems. As a result, the tools fail to cover all the necessarysafety properties for realistic real-time applications involving alarge number of components and tasks.

Runtime verification can thus be used as a complementor replacement for static verification approaches. The currentstate-of-the-art tools either do not have notion of time, or sufferfrom the potential blowup of states at run-time. In this paper,we propose REVERT, a framework developed with a focus onthe verification of functional and non-functional properties withtiming constraints. The contribution of this work is twofold: (i) adomain-specific specification language allowing the definition ofrequirements for real-time applications; (ii) a novel mechanism togenerate monitors, with statespace and time guarantees, capableof identifying and reacting to timing properties defined with theproposed specification language.

Although several static verification tools have been proposed over the last decades, they suffer from scalability and precision problems. As a result, the tools fail to cover all the necessary safety properties for realistic real-time applications involving a large number of components and tasks.

In this paper, we propose REVERT, a framework developed with a focus on the verification of functional and non-functional properties with timing constraints. The contribution of this work is twofold: (i) a domain-specific specification language allowing the definition of requirements for real-time applications; (ii) a novel mechanism to generate monitors, with state-space and time guarantees, capable of identifying and reacting to timing properties defined with the proposed specification language.
