Zusammenfassung
Cyber-physical systems are small yet powerful systems which are
embedded into their environment, adapting to its changes and at the same
controlling it, and often operating autonomously.
These systems have reached a level of complexity that opens up new
application areas, but at the same time
strains the existing design flows in system development. To ameliorate
this problem, we propose a novel design flow for cyber-physical
systems by adapting model-based specification and refinement methods
known from software development. The design flow allows to start with a
system specification and its essential properties at a high level of
abstraction, and gradually refines it down to an electronic system level.
Properties of higher levels can be inherited during refinements
to lower levels by relying on local proof obligations only, which results
in a design flow capable to keep up with the increasing complexity of
cyber-physical systems.
