Family-Based Model Checking of SPL based on mCRL2 Z. Ben Snaiba, E.P. de Vink, and T.A.C. Willemse We discuss how the general-purpose model checker mCRL2 can be used for family-based verification of behavioral properties of software product lines. This is achieved by exploiting a feature-oriented extension of the modal mu-calculus for the specification of SPL properties, and for its model checking by encoding it back into the logic of mCRL2. Using the example of the well-known minepump SPL an illustration of the possibilities of the approach is given.
