    This paper introduces Shelley, a novel model checking framework used to verify the order of function calls, developed in the context of Cyber-Physical Systems (CPS). Shelley infers the model directly from MicroPython code, so as to simplify the process of checking requirements expressed in a temporal logic. Applications for CPS need to reason about the end of execution to verify the reclamation/release of physical resources, so our temporal logic is stated on finite traces. Lastly, Shelley infers the behavior from code using an inter-procedural and compositional analysis, thus supporting the usual object-oriented programming techniques employed in MicroPython code. To evaluate our work, we present an experience report on an industrial application and evaluate the bounds of the validity checks (up to subsystems under 10 s on a desktop computer).
