Automata-based models of embedded systems are useful and attractive for many reasons: they are intuitive, precise, at a high level of abstraction, tool independent and can be simulated and analyzed. They also have the advantage of facilitating readability and system comprehension in the case of large systems. This paper proposes an approach for mining automata-based models from input/output execution...
This paper presents a novel approach to relate the variabilities that exist at the requirement and design levels in a Software Product Line (SPL). This approach is based upon two key observations: (i) it is not only the requirements, but also the design contain variability information, (ii) The variability information at the requirement and design levels are expressed differently and at different...
End-to-end latency of messages is an important design parameter that needs to be within specified bounds for the correct functioning of distributed real-time control systems. In this paper we give a formal definition of end-to-end latency, and use this as the basis for checking whether a stipulated deadline is violated within a bounded time. For unbounded verification, we model the system as a set...
