IP Core
Section 09: Hardware Certification (DO-254)
Definition
A pre-designed, reusable block of logic, cell, or chip layout design that is the intellectual property of one party and can be integrated into a larger hardware design. IP cores are categorized as soft cores (synthesizable HDL), firm cores (optimized netlist), or hard cores (physical layout). In avionics, IP cores may be vendor-supplied or developed in-house.
Where This Shows Up
The use of IP cores in DO-254 hardware designs presents certification challenges because the applicant must provide assurance for the entire design, including third-party IP. Vendor-supplied IP cores often lack the lifecycle data (requirements, design rationale, verification evidence) needed for DO-254 compliance. Strategies include obtaining lifecycle data from the IP vendor, performing additional verification at the integration level, or treating the IP core as a COTS component with appropriate risk mitigation. Reused IP cores from previously certified projects may qualify for credit based on demonstrated in-service experience.
