They are not so much interested in the detailed timing, i.e.
IEC 61508: Functional Safety of Electrical/ Electronic/Programmable Electronic Safety-related Systems (IEC61513 – specific to Nuclear Energy) IEC 987: Programmed digital computers important to safety in nuclear power plant.
..." Model-based testing relies on the use of behavior models to automatically generate sequences of inputs and expected outputs. The paper de nes an extension of the Hy Chart notation  with state-invariants.
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  with state-invariants.
First experimental results give rise to optimism w.r.t.
Among others, these include search strategies more powerful than backtracking alone, appropriate (graphical) input languages for test cases, and theoretical aspects such as the relationship between test cases (traces) and system specifications. This paper presents Hy ROOM, a proposal for an extension of UML-like languages by continuous activities for the specification of mixed discrete-continuous, or hybrid, systems.
It is implemented in a CASE tool prototype based on the Real-time Object Oriented Modeling methodology.
All vital parts ..." This paper presents Hy ROOM, a proposal for an extension of UML-like languages by continuous activities for the specification of mixed discrete-continuous, or hybrid, systems.
But as you probably know, optimally designed components do not necessarily result in optimal systems.Systems simulation can help to overcome this challenge. Test case generation for concurrent reactive systems on the grounds of symbolic execution basically amounts to searching their state space.As an application example we use a fictitious autonomous cruise control system (ACC).We argue that rapid prototyping approaches fit well with the use of models that serve as specifications, as basis for test case generation, or as basis for production code generation. Model-based testing relies on the use of behavior models to automatically generate sequences of inputs and expected outputs.It is shown how executable code for common Constraint Logic Programming languages can be generated automatically.
