Generating Requirements Documents for Embedded Systems: A Device Knowledge-Guided Approach

Requirements documentation is an important activity in requirements development. Embedded systems consists of software and hardware, as well as multiple stakeholders. As systems grow in size and complexity, writing requirements documents becomes more time-consuming and laborious. Based on the strong correlation between embedded system and physical device, this paper proposes to use device knowledge base to support requirements documentation. Stakeholders only need to fill in the intention and device selection, and then the device and system requirements are supplemented by device knowledge. Templates and environment modeling and analysis methods are proposed to further guide requirements acquisition. This leads to considerably simplify and accelerate the requirements document development for embedded systems.
