The standard that governs the design of avionic components and systems, DO-254, is one of the most poorly understood but widely applicable standards in the avionic industry. While information on the general aspects of the standard is easy to obtain, the details of exactly how to implement the standard are sketchy. And once an entity develops a process that achieves compliance, the details of how compliance was achieved become part of the intellectual property of that entity. This white paper focuses on the details of developing a DO-254 compliant process for the design of FPGAs.
