The invention discloses a civil aircraft requirement-oriented
numerical control system control software evidence chain development method. The method comprises the steps of developing and identifying
software requirements, establishing bidirectional
traceability of the requirements, developing requirement attributes of the
software, deriving feedback evaluation of the requirements, reviewing the requirements, and forming review instructions and review conclusions. According to the method,
engineering implementation steps of
software demand evidence chain development are clarified, the requirements of DO-178C for
software development process activities are implemented, and guidance is provided for civil aircraft
numerical control system software evidence chain development; a'
verification method 'and'
verification consideration' are established, the understanding and implementation effect of a demand developer on the demand are transmitted to
verification personnel, and the verification personnel are helped to improve the accuracy and sufficiency of case verification; and carrying out peer-to-
peer review of demand-by-demand and check-by-check items and forming a review description and a review conclusion, so that the deviation condition of the demand to the DO-178C target can be fully detected, and the achievement of the DO-178C target is ensured.
