In the present paper, we consider the task of creating hardware specifications for telecommunication devices that close the communication gap between hardware engineers and software developers. This task has arisen during the development of a family of telecommunication systems at Huawei. The specifications need to describe hardware from the viewpoint of driver development (i.e., device management), omitting many hardware details and including information for automatic generation of driver data structures and signatures. Furthermore, they need to be comprehensive and illustrative for both engineering groups. To meet this challenge, we propose a visual language supporting five views (representations): Structured view (all structural elements of a device), Composite view (all connections of a device), Datapath view (device parts that process the data flow), Control view (device parts that control the data flow processing), and Service view (device parts that provide additional functionality). We present an implementation of the visual language built with the Eclipse Modeling Tools Xtext/EMF/Sirius and integrated into a development environment for device management. We have received positive feedback from the device management software engineers.
