DO-330 Understanding: Software Tool Qualification Considerations

Posted on by

DO-330 is a set of considerations which can also be used outside airborne and ground based avionics systems.  It is not a supplement DO-178C & DO-278A like DO-331, 223, and 333. DO-330 was developed for the following reasons: Tools are different from the software developed using the tools and form a unique domain; therefore, tool-specific guidance for both tool developers and tool users is needed. Tools are often developed by teams other than those who use the tools to develop software. Typically, these tool development teams do not have software guidance backgrounds. Having a tool specific document helps tool development Continue Reading > > >

What is DO-254? Design Assurance Guidance for Airborne Electronic Hardware

Posted on by

What is DO-254? DO-254, “Design Assurance Guidance for Airborne Electronic Hardware,” was realeased in 2000 and formally recognized by the FAA in 2005 via AC-152 as a means of compliance. It provides guidance for the design of Complex Electronic Hardware (CEH) in airborne systems and equipment for use in aircraft or engines. DO-178 is the established software counterpart of DO-254. Functions are classified as either software or hardware, and governed by the processes provided by the guidance of either DO-178 or DO-254 accordingly. DO-254 Processes & Outputs The basic hardware design life-cycle processes are: The planning process. The hardware design Continue Reading > > >
