Do178Builder is a documentation tool used throughout the software/hardware development effort, helping to produce the DO-178B/254 documentation much less painfully. A major obstacle to creating airborne products, for smaller developers, is the necessity to qualify the software per RTCA/DO-178B, or hardware per RTCA/DO-254. Without this qualification, airborne products cannot be deployed.
