Research on Airborne Software Reuse Method Based on DO-178
Based on the DO-178B/C software reuse standard,previously developed software is divided into PDS that has passed the airworthiness certification and PDS that has not passed the airworthiness certification,and evaluation guidelines and evaluation methods for PDS is constrycted.By comparing the evaluation results with the standard,the reuse requirements of PDS and the process activities to be taken can be quickly located.The reuse practice shows that by reusing datum of the PDS that has passed the airworthiness certification,it can effectively improve the software development efficiency.A gap analysis method is also provided for the reuse of PDS that has not passed airworthiness certification,in which the gap between the PDS software and the target requirements is analyzed to assess the additional work required.
