The use of model checkers to solve discrete optimisation problems is appealing. A model checker can first be used to verify that the model of the problem is correct. Subsequently, the same model can be used to find an optimal solution for the problem. This paper describes how to apply the new Promela primitives of Spin 4.0 to search effectively for the… (More)
SpinJa is a model checker for promela, implemented in Java. SpinJa is designed to behave similarly to Spin, but to be more easily extendible and reusable. Despite the fact that SpinJa uses a layered object-oriented design and is written in Java, SpinJa’s performance is reasonable: benchmark experiments have shown that, in exhaustive mode, SpinJa is about… (More)
This paper concerns the transfer of les via a lossy communication channel. It formally speciies this le transfer service in a property-oriented way and investigates|using two diierent techniques|whether a given bounded retransmission protocol conforms to this service. This protocol is based on the well-known alternating bit protocol but allows for a bounded… (More)
ions As mentioned above, the state space of a model M together with the property φ to be checked, is generally too big to be checked exhaustively. In order to reduce the state space of the model M, abstractions have to be made. The verification approach requires over approximations of the original model Mv: if the abstract model Mabs is proven to be correct… (More)
Since the introduction of the rst version of the model checker Spin in 1991, many papers have been written on improvements to the tool and on industrial applications of the tool. Less attention has been given to the pragmatic use of Spin. This paper presents several techniques to optimise both the modelling and veri cation activities when using Spin.
Spin  is a model checker for the verification of distributed systems software. The tool is freely distributed, and often described as one of the most widely used verification systems. The Advanced Spin Tutorial is a sequel to  and is targeted towards intermediate to advanced Spin users.
M-health systems are safety critical systems intended for use by the public and are therefore characterized by especially strict requirements relating to safety, security, correctness, reliability, adaptability and user friendliness. This position paper proposes a methodology which realizes the MDA approach by utilizing formal methods to support… (More)
This tutorial consists of two parts. In the first part we present an advanced overview of Spin [1, 4], and illustrate its practical application to logic model checking problems. In the second part of the tutorial we present an overview of a related tool called Modex [2, 3]. Modex can be used to extract Spin verification models directly from C source code.… (More)
The Rigorous Examination of Reactive Systems’ (rers) Challenges provide a forum for experimental evaluation based on specifically synthesized benchmark suites. In this paper, we report on our ‘brute-force attack’ of the rers 2012 and 2013 Challenges. We connected the rers problems to two state-of-the-art explicit state model checkers: LTSmin and Spin. Apart… (More)
