Requirements traceability as defined in the RTCA/DO-254 document is quoted as follows:
RTCA/DO-254 page 66 10.4.1. Traceability Data Hardware traceability establishes a correlation between the requirements, detailed design, implementation and verification data that facilitates configuration control, modification and verification of the hardware item. Hardware traceability data should include:
A correlation between the system requirements allocated to hardware and the requirements.
A correlation between the requirements and the hardware detailed design data.
A correlation between the hardware detailed design data and the as-built hardware item or assembly.
A correlation between the requirements, including derived hardware requirements, and detailed design data and the verification procedures and results.
The results of a traceability analysis.
In other words, this means that the applicant must do the following:
Capture and manage FPGA requirements from the system spec
Establish links from requirements back to system spec
Establish links from requirements to conceptual design data
Establish links from requirements to detailed design data and implementation
Establish links from requirements to simulation and device testing results
Capture derived requirements and establish links to the detailed design data, implementation and results
Generate traceability reports
Manage and baseline requirements data and traceability links with appropriate configuration control
