Engenharia de requisitos baseadas em modelos para o domínio de software embarcado

Abstract

The design of an Embedded System has high complexity. It includes hardware, software and several functional or non-functional requirements. All requirements have to be well specified and managed during the whole project. In order to handle this complexity, description models are created using modeling languages such as UML. However, UML is neither able to represent non-functional requirements nor relationship between requirements. Therefore, management requirements are not supported on UML based approaches. The main objective of this work is to introduce a MDEReq approach that presents a model driven engineering requirements applied to embedded software. This approach provides requirements traceability that allows management of requirements from the specification to the validation. To support the complete requirement specification, UML diagrams are decorated with stereotypes of the MARTE profile, while the traceability is supported through the use of SysML notations. These models are integrated to ease the requirements traceability in all steps of the project. Furthermore, it allows the usage of a single tool for both design modeling and management requirements. One case study is used to demonstrate our approach.
