Project brief

A complete DO-254 Hardware Accomplishment Summary (HAS) and associated certification documentation package for a Design Assurance Level B ARINC 429 bus controller implemented in an Xilinx Artix-7 FPGA. The HAS summarizes how all DO-254 objectives were met from hardware planning through requirements, design, implementation, verification, and configuration management phases.

The case study concerns certification-support documentation for a specified hardware baseline. It does not imply a new approval or independently verified compliance finding.

The engineering challenge

Summarize hardware lifecycle evidence without losing the trace from requirements to design and verification.

Engineering approach

  1. Organize planning, requirements, implementation, and verification references.
  2. Connect configuration records and problem reports to the hardware baseline.
  3. Present objective-by-objective evidence and audit preparation material.

Features & capabilities

  • Hardware Plans: PHAC, HVP, HCMP, HDC — 4 plan documents
  • Hardware Requirements Document (HRD): 143 HRDs traced to system requirements
  • Hardware Design Document (HDD): schematic, FPGA architecture, PCB layout
  • Hardware Verification Results (HVR): test cases, procedures, and results
  • Configuration Management Records: version control, problem reports, change history
  • Tool Qualification Records for HDL simulator and synthesis tool
  • Traceability matrices: system req → HRD → design → verification (bidir)
  • Stage of Involvement (SOI) audit preparation and response documentation
