Preparing for AEH DO-254 SOI-3
Process Assurance is a really important role in a DO-254 program. (Likewise, Quality Assurance in a DO-178C program). If done well, it can save companies a lot of time and expense by making SOI audits [...]
Why Do Target Testing?
A common inquiry from applicants is whether they have to do target testing, and if so, why, and how much to do. RTCA/DO-254, along with FAA Order 8110.105A, both emphasize the expectation that the testing [...]
What the Heck is a “Top-Level Drawing” of an FPGA?
If you’re new to DO-254, and you’re reading the document you will stumble upon multiple references to a Top-Level Drawing. In the discussion of Detailed Design Data, you will be asked to create a Top-Level [...]
