Stress-Relief for Requirements-Based Verification

 
July 16th, 2014 by Louie De Luna

DO-254-RequirementsIf they’re being honest, anyone who has verified an FPGA under strict DO-254 guidance will tell you that it is stressful. Show me an engineer on their first DO-254 project – and I’ll show you someone pulling out their hair and downing what is probably their 5th cup of coffee while these important questions weigh heavy on their minds:

Have we reviewed all FPGA requirements and validated derived FPGA requirements? Do we have a good record of the review activities?

Do I have a test for each functional FPGA requirement? What’s the status of the tests? How do I track the progress and document the results?

How do I manage traceability and create traceability matrices?

What are the differences between the requirements baseline from SOI#2 and the requirements baseline from SOI#3?

What design and verification elements are impacted due to a requirement change?

These questions might sound scary to anyone new to DO-254, however they can be answered simply by understanding the primary processes involved and by having a well-defined set of deliverables. The processes and deliverables for requirements-based verification are: Requirements Capture and Allocation, Requirements Review and Validation, Test Planning and Management, Traceability, Defect Management and Coverage Analysis.
