These sequences can be used as test cases to the end of both validating the model and also verifying an actual system. Hy Charts are a graphical, modular, and formal description technique for the speci cation of hybrid, i.e. Methodological issues arising from the extension are discussed. The paper de nes an extension of the Hy Chart notation [8] with state-invariants.

At the same time, these functional safety standards introduce a number of challenges for engineers and organizations developing these safety critical electronic components.

Applications include simulation for rap ..." The CASE tool Auto Focus allows for modeling and validating concurrent reactive systems on the basis of a simple, clearly defined formal semantics.

Applications include simulation for rapid prototyping and debugging as well as the semi-automatic generation of test sequences. In the domain of reactive systems, work on validation has mainly focused on verifying specifications.

Furthermore, we provide a clear terminology for concepts within the testing context. Model-based testing relies on the use of behavior models to automatically generate sequences of inputs and expected outputs.
