Simulink/Stateflow charts are widely used in industry for the specification
of control systems, which are often safety-critical. This suggests a need for a
formal treatment of such models. In previous work, we have proposed a technique
for automatic generation of formal models of Stateflow blocks to support
refinement-based reasoning. In this article, we present a refinement strategy
that supports the verification of automatically generated sequential C
implementations of Stateflow charts. In particular, we discuss how this
strategy can be specialised to take advantage of architectural features in
order to allow a higher level of automation.Comment: In Proceedings Refine 2011, arXiv:1106.348
