Along with the popularity of software-intensive systems, the interactions between system components and between humans and software applications are becoming more and more complex. This results in system accidents related to system safety issues. System accidents are different to failures related to component reliability. System safety is not well addressed, because functional requirements and safety...
For the development of component-based safety critical systems, not only consistency and compatibility among component interfaces, but also safety requirements of system need to be verified after components composition. This paper proposes a light-weight formal verification framework focusing on industry application, safety requirements specification through graphical PSC(Property Sequence Charts),...
With rapid developments in science and technology, we now see the ubiquitous use of different types of safety-critical systems in our daily lives such as in avionics, consumer electronics, and medical systems. In such systems, unintentional design faults might result in injury or even death to human beings. To make sure that safety-critical systems are really safe, only using the traditional methods...
We present a component-based description language for heterogeneous systems composed of several data flow processing components and a unique event- based controller. Descriptions are used both for generating and deploying implementation code and for checking safety properties on the system. The only constraint is to specify the controller in a synchrounous reactive language. We propose an analysis...
Systems verification requires first to model the system to be verified, then to formalize the properties to be satisfied, and finally to describe the behaviour of the environment. This last point, known as the proof context, is often neglected. It could, however, be of great importance in order to reduce the complexity of the proof. The question is then how to formalize such a proof context. This...
