New Requirement Definition and Verification Techniques According to DO-178C, DO-331, and DO-333

In this paper, a model-based tool chain for DO-178C-compliant development is presented which can be used to design, implement and verify software up to DO-178C Level A. The tool chain is based on the "model-based supplement" DO-331 as well as the "formal methods supplement" DO-333 and makes use of model-based design and verification techniques as well as automatic production code generation and model checking to develop safety-critical software with high efficiency.
