Sample interview questions: How do you ensure that hardware designs are compliant with functional safety standards for aerospace functional safety (e.g., DO-178)?
Sample answer:
Ensuring Compliance with Functional Safety Standards
Adherence to DO-178 for Aerospace Hardware Designs
1. Development and Maintenance of Lifecycle Traceability:
– Establishing a comprehensive traceability matrix linking hardware requirements to system requirements, design specifications, and test results.
– Implementing a system for tracking changes and maintaining the traceability throughout the development lifecycle.
2. Formal Verification and Validation:
– Conducting rigorous formal inspections and reviews of hardware designs against functional safety specifications.
– Employing static analysis tools, simulation, and testing to validate the design’s compliance with safety requirements.
3. Hazard Analysis and Risk Assessment:
– Performing thorough hazard analyses to identify potential failures and their impact on system safety.
– Quantifying risks and implementing mitigation measures or design changes to reduce or eliminate hazards.
4. Hardware Safety Planning:
– Establishing a comprehensive hardware safety plan that defines the deve… Read full answer
