What is do330?
DO-330 provides tool-specific guidance for building airborne and ground-based software. It may also be used by other domains such as automotive, space, systems, electronic hardware, aeronautical databases, and safety processes.
What is Tool confidence level?
Tool Confidence Level: TCL 1 is the lowest level of confidence. Tools assigned this level do not have high impact on the quality of the final product. Therefore, tool qualification is not required. TCL 2 and 3 are medium and high level of confidence, respectively.
What is the code coverage for DO-178B?
Catastrophic (level A), hazardous-severe (level B), major (level C), minor (level D) or no-effect (level E). According to the DO-178B-level the following test coverage (code coverage) is required : DO-178B Level A: Modified Condition Decision Coverage (MC/DC) Branch/Decision Coverage Statement Coverage DO-178B Level B:
What do I need to get a DO-178B certification?
Statement Coverage To obtain a DO-178B certification the software and a number of supplementary documents and quality proofs (among them test protocols) have to be provided. In order to limit the expenditures the usage of professionnal tools is essential.
Can you apply DO-178B reverse engineering to your existing software?
Can you apply DO-178B reverse engineering to your existing software? Yes, while DO-178B applies principally to new, custom software, there are provisions to apply DO-178B reverse-engineering to previously developed software, preserving most of the already completed work.
How much does DO-178B add to avionics development?
DO-178B is often thought to add 50-200% to avionics software development. In reality, actual additional DO-178B cost should be on the order of 25%-40%, presuming basic high-reliability (SEI CMM and CMMI Level 2 or 3) software engineering principles are used from the onset.
