Reused Hardware Logic
Section 09: Hardware Certification (DO-254)
Definition
Previously developed hardware design elements, including HDL modules, schematics, or IP cores, that are incorporated into a new hardware design. Reuse may involve using the design in a new application context, a different technology (e.g., migrating from one FPGA family to another), or a different design assurance level.
Where This Shows Up
DO-254 Section 11.1 addresses previously developed hardware. Credit for reuse depends on the availability of lifecycle data from the original development, the degree of change in the new application context, and whether the original design was developed to an equivalent or higher assurance level. A change impact analysis must be performed to identify differences in requirements, environment, technology, or tools that could affect the validity of prior verification evidence. Even with significant reuse credit, integration-level verification in the new context is always required.
