The standard itself. Available for purchase from RTCA. Required reading — not optional, not summarizable.

European equivalent to DO-254. Technically identical content. Required for EASA certification paths.

The software counterpart. Relevant when your FPGA contains embedded processors or when software/hardware partitioning decisions affect your PHAC.

System-level development process. This is where your DAL assignment originates. Understanding 4754A helps you understand why your DAL is what it is.

Safety assessment methodology. FTA, FMEA, FMES. The analysis that feeds into your DAL assignment and drives your PHAC safety objectives.

FAA Advisory Circular recognizing DO-254 as an acceptable means of compliance. This is the document that connects the standard to the regulatory framework.

FAA order defining the approval process for electronic hardware including FPGAs. Defines the role of the DER and the SOI review process.

Internal FAA job aid for DERs reviewing DO-254 compliance. Not officially public guidance, but widely circulated and useful for understanding what DERs look for.

Position paper on multi-core interference. Increasingly being applied to FPGA designs with multiple independent clock domains and shared resources.

CAST position paper specifically addressing complex electronic hardware development. Provides interpretive guidance on DO-254 objectives.

Tool qualification data and compliance documentation for Vivado. Available for UltraScale+, Versal, and older device families. Contact AMD for access.

DO-254 compliance documentation for Quartus Prime. Recently released for Agilex 5 and 7 families. Covers synthesis, fitter, and timing analyzer.

DO-254 support for PolarFire and SmartFusion2 families. Flash-based architecture provides configuration security advantages relevant to PHAC safety arguments.

Purpose-built DO-254 tools including requirements tracing, structural coverage analysis, and certification artifact generation. One of the few vendors focused specifically on this problem.

GTH/GTY transceiver design, JESD204C, protocol compliance. Relevant when your DO-254 design includes high-speed serial interfaces.

ISO 26262 for FPGA. Different standard, overlapping methodology. Useful comparison for engineers working across automotive and avionics programs.

JESD204B/C converter interfaces, multi-device synchronization, deterministic latency. Common in avionics RF and radar FPGA designs.
