Since the release of DO-178B, there have been strong calls by DERs (FAA Designated Engineering Representatives) for clarification/refinement of the definitions and boundaries between the key DO-178B concepts of High Level Requirements, Low Level Requirements, and Derived Requirements and a better definition of the exit/entry criteria between systems requirements and system design (see ARP4754) and that of software requirements and software design (which is the domain of DO-178B). Other topics such as what does verification mean in a model-based development paradigm and can model simulation or formal methods replace some or all software testing activities. The release of DO-178C and the companion documents DO-278A (Ground Systems), DO-248C (Additional information), DO-330 (Tools), DO-331 (Modeling), DO-332 (Object Oriented), and DO-333 (Formal Methods) were created to address the criticisms noted.
