“…Compatibility here means satisfiability of an item of the setT as defined by Eq. (1), and it is checked by the simple program sat p q t = p L && (q (snd (step t L I))) where L,I free (5) where p and q are the programs that characterize source and destination states, t ranges over all possible transitions, L denotes the vector of all local variables, and I is the input. L and I are computed automatically by the Curry runtime system.…”

“…Consequently, there is a plethora of tools that enable one to specify systems with these languages. Behavior models are then used to generate simulation and production code [5,14,15] or test cases [4,16,37,38]. They are also subjected to formal verification technology such as model checking [8,12] or automated deductive theorem proving [2,3].…”

For behavior models expressed in statechartlike formalisms, we show how to compute semantically equivalent yet structurally different models. These refactorings are defined by user-provided logical predicates that partition the system's state space and that characterize coherent parts -modes or control states -of the behavior. We embed the refactorings into an incremental development process that uses a combination of both tables and graphically represented state machines for describing systems.

Through the introduction of model-based development, paradigm models became first class citizens in the development of invehicle software and are thus also object to strict quality assurance. Just as code reviews are widespread in classical software development, models also have to undergo a stringent review procedure -particularly if they serve as a basis for automatic software implementation by means of model-based code generators. In addition to model reviews, the generated production code (autocode) must be reviewed by performing so-called autocode reviews. This paper presents our procedure for a combined model and autocode review and provides examples, lessons learned, as well as significant experimental results drawn from a typical automotive embedded software development project.

We are concerned with systems, particularly safety-critical systems, that involve interaction between users and devices, such as the user interface of medical devices. We therefore developed a MISRA C code generator for formal models expressed in the PVSio-web prototyping toolkit. PVSio-web allows developers to rapidly generate realistic interactive prototypes for verifying usability and safety requirements in human-machine interfaces. The visual appearance of the prototypes is based on a picture of a physical device, and the behaviour of the prototype is defined by an executable formal model. Our approach transforms the PVSio-web prototyping tool into a model-based engineering toolkit that, starting from a formally verified user interface design model, will produce MISRA C code that can be compiled and linked into a final product. An initial validation of our tool is presented for the data entry system of an actual medical device.
