This paper presents a UML implementation of the MDETools’19 challenge problem with EMI (our Embedded/Experimental Model Interpreter). EMI is a model interpreter that can be used to execute, simulate, and formally verify UML models on host or embedded targets. The tool’s main specificity relies on a single implementation of the language semantics such that consistency is ensured between all development phases: from design to verification and execution activities. Using this approach, we have succeeded in (i) designing a UML model for the challenge problem, (ii) applying formal verification using model-checking on the design model, and (iii) executing this model in order to participate in the challenge.
