DO-254 Training: Avionics Hardware

DO-254 is often referred to as the counterpart to the software standard DO-178C.

That’s because DO-254 helps by providing direction for design assurance of airborne electronic hardware. It also provides you with certification information from the beginning of your project through validation.

Developed by the RTCA in 2000, DO-254 was prompted by the need to address potential safety issues regarding electronic hardware – chips, boards and boxes. It is now required on all civil aircraft types, including helicopters, and the military is adopting it as well.

Before DO-254 avionics software was governed by DO-178B, but equally complex, silicon-based logic or firmware, was unregulated.

In the early years, because many players considered DO-254 too oppressive, the standard was evaded or ignored. Finally, in 2005, the FAA mandated DO-254.

Today, experts in this standard insist that the requirement terminology is important in the DO-254 process, and helps identify where documentation and verification effort is required, versus where precedent and experience may be sufficient. For example:

  • Certified: An entire system is certified and components may have different certification levels
  • Certifiable: System component achieving its highest certification status before certifying it within the system
  • Qualified: Certification of a tool that does not have safety requirements

Most notable in the DO-254 standard is the five levels of compliance, A to E. Each level depends on the effect a failure of the hardware will likely have on the operation of the aircraft. Level A is the most stringent level of compliance. This refers to a catastrophic effect such as loss of the aircraft. At the other end, Level E hardware failure is classified as not impacting the safety of the aircraft.

Consequently, meeting Level A compliance for complex electronic hardware requires a much higher level of verification and validation than Level E compliance.

DO-254 Training: Avionics Hardware Course Description

DO-254 Training: Avionics Hardware discusses various angles of DO-254 guideline and will help you develop and implement this standard in your organization.

DO-254, aka Eurocae ED-80, is an official avionics guideline, which demonstrates strategies of design assurance associated with airborne electronic hardware. DO-254 covers the required information comprehensively from the conceptual design, through planning, designating, executing, verifying, to validation. It also contains DO-254 Tool Qualification considerations. Presently, it is mandatory for most avionics projects to comply with a DO-254 certification. DO-254 training will help you fully learn all of these steps to execute in your own organization.

DO-254 Tool Qualification

Developing hardware demands using several tools including the tools for design, implementation, synthesis, simulation, libraries, verification, and physical coverage. DO-254 tool qualification relates to developing and verifying such tools. Various qualification requirements pertain to each, while most tools do NOT need to be qualified. But if necessary or mandated, DO-254 tool qualification uses a subset of DO-254. DO-254 training will also cover this part of the DO-254 guideline to ensure you are able to apply DO-254 Tool Qualification procedure when required.

TONEX Hands-On Workshop Sample

Assume that you have a client that is a principal aerospace provider located in the USA. Their goal is to design a system that links aircraft with ground-based channels. They hire you to execute DO-254 advanced verification methodology in order to confirm their FPGA design in time for the product release.

  • Develop Constrained Random Verification (CRV) method for verifying FPGA design
  • Design and develop a reusable structure to facilitate changes in requirements
  • Verify the requirements
  • Consider EASA robustness specifications
  • Discuss which tools you are going to use
  • Apply all the DO-254 steps
