Expression and validation of timing constraints and integration in software specification methods

The specification of temporal properties covers two issues: the expression and the validation in a machine-independent way. Common sense associates real-time to fast computing. Real-time contains two aspects: the problem of the coherence of temporal constraints between themselves and the performance constraints of the system. We propose a method that makes that distinction in order to decrease the complexity of the real-time application and replaces each problem at the best step of the life cycle of the application. The originality of this specification method is to express temporal properties in a formal manner that handles time in a qualitative and pseudo-quantitative way.<
