We give a detailed description of SymmSpin, a prototype implementation of a symmetry-reduction package for the Spin model checker. It offers several heuristics for state-space reduction. A series of experiments is described, underlining the effectiveness of the heuristics and demonstrating the ability of the implementation to handle almost all of Spin’s(More)
The problem of job stress is generally recognized as one of the major factors leading to a spectrum of health problems. People with certain professions, like intensive care specialists or call-center operators, and people in certain phases of their lives, like working parents with young children, are at increased risk of getting overstressed. For instance,(More)
The SACRES project is an Esprit R&D project, SACRES members are : Siemens ( Lead partner), i-Logix, TNI (Techniques Nouvelles d'Informatique), OFFIS, INRIA, the Weizmann Institute of Science, British Aerospace, SNECMA. As its name indicates, SACRES is dealing with the development of new design methodologies and associated tools for safety critical embedded(More)
– event synchronization: the process is always able to react to events of the environment at a rate determined by the environment; – response synchronization: the response synchronizes properly with the environment, i.e., the time elapsed between a stimulus and the response of the process is short enough (relatively to the dynamics of the environment) so(More)
The use of systematic testing and formal verification in the validation of reactive systems implemented in synchronous languages is illustrated. Systematic testing and formal verification are two techniques for checking the consistency between a program and its specification. The approach to validation is through specification: two system views are(More)
