Abstract : In embedded systems, non-functional and functional aspects are closely related and cannot be considered independently. However, the high complexity of systems requires a large domain of competencies and experts in various domains have to work concurrently on different aspects of the same systems. This is why we propose a multi-view model where each view represents a specific domain. The different views are connected to each other by explicit associations that maintain consistency. The whole system is the sum of all the aspects of elements in all the views. This multi-view approach is implemented in a dedicated UML profile based on MARTE and SysML. This article specifically focuses on the power view and its relationship to other functional or non-functional, structural or behavioral aspects.
