The Research of Use Case Approach for Software Requirement of Embedded System
The use case approach is a commonly used software requirement modeling method,but due to the limited number of traditional use cases in embedded systems and the fact that the use case approach does not require determining the data domain of the entire software,it is rarely used to analyze the software requirements of embedded systems.This article draws on the approach of the structured incentive response method in the first step of"decomposing system requirements"and the fourth step of"determining software data domains",using embedded systems or modules or machines affected by them,as well as different modes of these modules or machines,as use case roles.Through grouping use case inputs and outputs,defining incentives and responses,and forming a"vocabulary"and"data dictionary"for the entire software,the use cases of embedded system software are obtained and analyzed for requirement modeling.Finally,taking a communication module supporting software as an example,demonstrate the above process.
