We report on an industrial application of UPPAAL, in which a commercial field bus protocol (AF100) is modelled and analysed using the tool. During the case study, a number of imperfections in the protocol logic and its implementation are found and the error sources are debugged based on abstract models of the protocol; respective improvements have been suggested. In this paper, we shall summari...

This is a tutorial paper on the tool Uppaal. Its goal is to be a short introduction on the flavor of timed automata implemented in the tool, to present its interface, and to explain how to use the tool. The contribution of the paper is to provide reference examples and modeling patterns.

We present the formal speciication and veriication of a lip synchronisation algorithm using the real-time model checker UPPAAL. A number of speciications of this algorithm can be found in the literature, but this is the rst automatic veriication. We take a published speciication of the algorithm, code it up in the UPPAAL timed automata notation and then verify whether the algorithm satisses the...

To combat the state-explosion problem in automatic verification, we present a method for scaling up the real-time verification tool Uppaal by complementing it with methods for abstraction and compositionality. We identify a notion of timed ready simulation which we show is a sound condition for preservation of safety properties between realtime systems, and in addition is a precongruence with r...

This contribution reports on the considerable effort made recently towards extending and applying well-established timed automata technology to optimal scheduling and planning problems. The effort of the authors in this direction has to a large extent been carried out as part of the European projects Vhs [22] and Ametist [17] and are available in the recently released Uppaal Cora [12], a varian...

With the support of emerging technologies such as 5G, machine learning, edge computing and Industry 4.0, Internet Things (IoT) continues to evolve promote construction future networks. Existing work on IoT mainly focuses its practical applications, but there is little research modeling interactions among components in systems verifying correctness network deployment. Therefore, Calculus (CaIT) ...

Context: The goal of specification pattern catalogs for real-time requirements is to mask the complexity specifying such in a timed temporal logic verification. For this purpose, they provide frontends express and translate pattern-based natural language formulae suitable logic. However, widely used model checking tool UPPAAL only supports restricted subset those that focus on basic non-nested ...

Uppaal is a tool suitable for model checking real-time systems described as networks of timed automata communicating by channel synchronizations and extended with integer variables. Its first version was released in 1995 and its development is still very active. It now features an advanced modelling language, a user-friendly graphical interface, and a performant model checker engine. In additio...
