Description/Abstract

Making the step from Event-B to code is a process that can be aided through automatic code generation. The code generation plug-in for Rodin is a new tool for translating Event-B models to concurrent programmes. However users of such a tool will likely require a diverse range of target languages and target platforms, for which we do not currently provide translations. Some of these languages may be subtly different to existing languages and only have modest differences between the translation rules, for example C and C++, whilst others may have more fundamental differences. As the translation from Event-B to executable code is non-trivial and to reduce the likelihood of error, we want to generalise as much of the translation as possible so that existing translation rules are re-used. Therefore significant effort is needed to ensure that such a translation tool is extensible to allow additional languages to be included with relative ease. Here we concentrate on translation from a previously defined intermediary language, called IL1, which Event-B translates to directly.
