1. Purpose

This document provides the bidirectional traceability matrix required by ISO 26262 Part 8 Clause 6 and ASPICE generic practices (GP 2.2.4). It traces from system requirements through software requirements, detailed design, implementation, and test cases, enabling complete forward and backward navigation of the requirement chain.

2. Scope

The matrix covers all requirements from SYS.2-001 (system requirements), SWE.1-001 (software requirements), ISO-SSR-001

(safety requirements), and their traces to design (SWE.3-001), code modules, and test cases (SWE.4-001, SWE.5-001, SWE.6-001).

4. Traceability Convention

Each row traces one requirement through the full chain:

System Req (SYS-REQ-xxx) -- from SYS.2-001
Software Req (SW-REQ-xxx) -- from SWE.1-001
Safety Req (SSR-xxx) -- from ISO-SSR-001

9. Acceptance Criteria

This traceability matrix is accepted when:

Every system requirement (SYS-REQ-xxx) traces forward to at least one software requirement and one test case.
Every ASIL D software requirement (SW-REQ-xxx) traces forward to at least one test case.
Every safety requirement (SSR-xxx) traces forward to at least one test case.
Every test case (UT/IT/QT) traces backward to at least one requirement.
All identified gaps have documented remediation plans.
