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 …

Formal methods and testing are two important approaches that assist in the development of
high-quality software. While traditionally these approaches have been seen as rivals, in …

We present a generalization of the classical theory of testing for Mealy machines to a setting
of dense real-time systems. A model of timed I/O automata is introduced, inspired by the …

We propose a new framework for black-box conformance testing of real-time systems, where
specifications are modeled as non-deterministic and partially-observable timed automata …

We propose a new framework for black-box conformance testing of real-time systems. The
framework is based on the model of partially-observable, non-deterministic timed automata …

Verification by state-space exploration, also often referred to as model checking, is an
effective method for analyzing the correctness of concurrent reactive systems (for instance …

Model-checking is a successful technique for automatically verifying concurrent finite-state
systems. When designing a model-checker, a good compromise must be made between the …

To become practical for assurance, automated formal methods must be made more
scalable, automatic, and cost-effective. Such an increase in scope, scale, automation, and …

This paper presents an overview on the IF toolset which is an environment for modelling and
validation of heterogeneous real-time systems. The toolset is built upon a rich formalism, the …

Labelled transition system based test theory has made remarkable progress over the past
15 years. From a theoretically interesting approach to the semantics of reactive systems it …
