摘要
DO-178B机载设备软件的开发指南,规定了软件生存周期中各个过程的目标以及完成目标的活动和证据;但是DO-178B标准中没有给出软件需求获取的具体过程。针对机载设备软件AE653/Cert的认证过程进行研究,诠释需求获取过程中的建模方法和原则,给出需求获取过程的具体描述及其变更控制和配置管理。最后通过分析验证软件需求获取过程生成的需求和工作产品可以符合DO-178B的目标,为机载软件开发过程的需求获取提供了参考依据。
DO- 178B is a development guidance of airborne system and equipment, it describes the objectives of software life cycle processes and the activities and proof to achieve those objectives. However the acquisition process of software requirement is not regulated in DO- 178B. Aiming at the certification process of airborne system AE653/Cert, the modeling method and principle of requirement acquisition process are firstly annotated. Then the specific requirement acquisition process is described and its change control and configuration management are given. Finally, the requirement artifact derived from software requirement acquisition process are analyzed and identified to comply with the objective of DO -178B ,thus it provides reference basis for the requirement acquisition of airborne system.
