In this paper we discuss an approach for requirements traceability in a model-based testing process. We show how the informal requirements of the system under test evolve and are traced at different steps of the process. More specifically, we discuss how requirements are traced to system specifications and from system specification to tests during the test generation process, and then how the test...
We propose an approach to specifying embedded devices based on the Network on Terminal Architecture (NoTA) and show how the approach allows the specification of NoTA components, including service interfaces, and timing and energy consumption constraints. The purpose of such specifications is two fold: to enable vendors to provide already tested component implementations with respect to specifications,...
We discuss a design process for a custom distributed platform, namely the SegBus segmented bus architecture. The main emphasis of this work is on how different steps of the process are interconnected and how they are supported by the associated tool chain. We place the SegBus design process in the context of the model-driven architecture (MDA) paradigm, in order to provide graphical editors that allow...
We discuss a design methodology for SegBus, a multicore segmented bus platform. The methodology supports the modeling of the platform at several abstraction levels, enabling the designer to focus only on the relevant aspects of the architecture at a given development stage. We employ the unified modeling language (UML) as a specification language for the SegBus platform and we customize its elements...
