Verifying system-wide properties of industrial component-based software

Analytical Software Design (ASD) enables model-based development of component software systems. Until now, functional verification of ASD systems is only possible on a per-component basis. There is no functional verification engine for ASD itself, so this verification relies on a translation of individual components to mCRL2, a process-algebraic model checker. We show how to extend the ASD-mCRL2 translation to support multiple components in order to enable checking of system wide functional properties. With our extended translation, we perform a case-study on a newly developed industrial system consisting of 26 communicating components. The results indicate that it is feasible to model check functional properties on this scale.
