From requirements to code (Re2Code): A model-based approach for controller implementation

This paper presents a step by step model based approach (Re2Code) allowing the translation from Problem Frames, supporting requirements, to executable code for embedded controllers. The approach uses a set of heuristics to translate Problem Frames diagrams and requirements, into executable Input-Output Place-Transition (IOPT) net models, which take advantage of concepts available in IOPT nets, namely input and output events, and states. The IOPT nets models are then translated to executable C code, relying on the availability of a free translator (IOPT tools) from IOPT net models to C code, thus providing a support for the implementation of Cyber-Physical Systems. An example illustrates the approach
