Most recently, we have developed a translator from Lustre to the SAL (Symbolic Analysis Language) developed by SRI International, allowing us to use the model checkers and theorem provers included in the SAL toolset. We have also developed translators from the Reactis test case generation tool to Lustre, providing an alternative path from Simulink to Lustre. This translator is being extended to support a subset of StateFlow models as well as Simulink.
