Airborne software tool qualification analysis and application based on DO-330

Abstract

With the increase of software tools used in the airborne software development and verification process to meet DO-178C, in order to ensure its airworthiness and safety, DO-330 is taken as a guide for software tool qualification process of DO-178C. At present, the commercial off-the-shelf (COTS) tools cannot meet the requirements of specific project development and verification. The evaluation tool qualification level, life cycle process and objective of tool qualification in DO-330 are used as the guidance basis. The main concerns and difficulties in the process of DO-330 engineering practice are analyzed. Combined with the actual project, the qualification process of self-developed tool to meet the requirements of DO-330 is given. The results show that the self-developed tool qualification of tool qualification level 5 (TQL-5) proposed in this paper has engineering feasibility, and has made substantial progress, which provides reference and guidance to meet specific project requirements and perform software tool qualification according to DO-330 requirements.
