Specification and verification of time requirements with CCSL and Esterel
Charles André, Frédéric Mallet · 2009
The UML Profile for Modeling and Analysis of Real-Time and Embedded (MARTE) systems has recently been adopted by the OMG. Its Time Model extends the informal and simplistic Simple Time package proposed by UML2 and offers a broad range of capabilities required to model real-time systems including discrete/dense and chronometric/logical time. MARTE OMG specification introduces a Time Structure inspired by Time models of the concurrency theory and proposes a new clock constraint specification language (CCSL) to specify, within the context of UML, logical and chronometric time constraints.
