Two Semantic Models for Clock Relations in the Clock Constraint Specification Language
Résumé
The Clock Constraint Specification Language (CCSL) has been defined as a formal companion language of the UML Profile for MARTE to allow defining causal and temporal constraints. This chapter attempts to refine the mathematical foundations of the time model of CCSL. It proposes two semantic models both considering ordered binary relations on CCSL clocks and establishes the equivalence of the two models.
