Functionality: Formal Analysis of Distributed Reactive Applications

Tools used: CADP (Construction and Analysis of Distributed Processes)

Period: 2017

Description: Compositional verification techniques are a useful approach to cope with the limitations of formal verification of complex component-based systems. However, as they are generally applied on abstract models rather than the concrete system components, the analysis and prediction of inter-dependencies of the overall system is still challenging. Therefore the authors promote a correct-by-construction approach, providing design rules to build correct systems from correct components.

Components of a distributed reactive application are modeled as I/O automata, akin to synchronous dataflow models called SR-models. Each component has its own set of parameters (latency and memory). Composition rules ensure composability and guarantee correct composition of SR-models.

The proposed framework comprises two main activities. First, the construction of the model. To increase the reusability, a library of previously designed and verified components helps in the construction. Second, the verification of the global model relies on the automatic analysis enabled by model-checking with CADP.

The proposed framework is illustrated on an Inverse Discret Cosine Transform.

Conclusions: The CADP toolbox "offers a wide range of functionalities among which model checking and equivalence checking".
