Correctness of an ATL Model Transformation from SysML State Machine Diagrams to Promela
Georgiana Caltais, Stefan Leue, Hargurbir Singh · 2020
In this paper we discuss the correctness of an ATL-based model transformation from the systems engineering modelling language SysML into Promela, the input language of the SPIN model checker. More precisely, we reduce showing the correctness of the transformation to showing a notion of what we refer to as observational equivalence of the SysML and the generated Promela models, respectively. This paves the way to a proof technique that could be further exploited in order to argue the correctness of model transformations from SysML to various model checkers, based on the observable actions generated by the systems under analysis.
