Abstract: CCSL has arisen from different inspiring models in an attempt to abstract away the data and the algorithms, and to focus on events and control. Even though CCSL was initially defined as the time model of the UML profile for MARTE, it has now become a full-fledged domain-specific modeling language for capturing causal, chronological and timed relationships. It is intended to be used as a complement of other syntactic models that capture the data structure, the architecture and the algorithm.
This work starts by describing the historical models of concurrency that have inspired the construction of CCSL. Then, CCSL is introduced and used to build libraries dedicated to two emerging standard models from the automotive (East-ADL) and the avionic (AADL) domains. Finally, we discuss an observer-based technique to verify implementations in different languages (Esterel, VHDL) against a CCSL specification.
