Model checking of Scenario-Aware Dataflow with CADP

2012 2012 Design, Automation & Test in Europe Conference & Exhibition (DATE)  
Encountered challenges included dealing with probabilistic choice and potentially unbounded buffers, both of which are not natively supported, as well as a fundamental difference in the underlying time  ...  To this end, we propose a compositional IMC semantics for SADF based on which the Construction and Analysis of Distributed Processes (CADP) tool suite enables model checking various properties.  ...  The original semantics of SADF is defined in terms of so-called Timed Probabilistic Systems [36] . They contain action, probabilistic and deterministic time transitions.  ...
