Towards Generating SPARK from Event-B Models

This paper presents an approach to generate SPARK code from Event-B models. System models in Event-B are translated into SPARK packages including proof annotations. Properties of the Event-B models such as axioms and invariants are also translated and embedded in the resulting models as pre- and post-conditions. This helps with generating SPARK proof annotations automatically hence ensuring the correct behaviour of the resulting code. A prototype plug-in for the Rodin has been developed and the approach is evaluated on different examples. We also discuss the possible extensions including to generate scheduled code and data structures such as records.
