Abstract

The combination of embedded systems with physical components, termed Cyber-Physical Systems (CPSs), poses important challenges in the design, modelling, simulation and verification of systems, because they combine discrete software elaborations with analogues time evolutions and different engineering disciplines. The increasing importance of the software components in CPSs determines needs for modelbased tool supporting in the design and integration of the artefacts from different disciplines. We presented within the framework of FOCUS modelling theory a logical representation of software-intensive CPSs: hybrid i/o state machines. We introduced algorithms for the simulation of such state machines a modelling support tool. In early development phases test and validation of software-intensive CPSs, before the final hardware deployment permits an agiler and more efficient design. In this paper we analyse a preliminary implementation of our sampling algorithms with a focus on performance and scalability aspects. We compare the results with dynamic sampling algorithms used in MATLAB Simulink/Stateflow that is de facto an industrial standard for the design of embedded systems.
