ISO 26262 software evidence needs an allocated safety requirement.
Connect the software change to the safety behavior it serves, then inspect the relevant implementation and verification under the project’s agreed scope.
Keep Part 6 within the wider lifecycle.
ISO 26262-6:2018 addresses software-level product development for automotive functional safety. ISO’s public scope includes software safety requirements, architecture, unit verification, integration and embedded-software testing.
Source: ISO: ISO 26262-6:2018. Scope and edition reviewed 3 October 2026.
The safety classification, applicable methods and project responsibilities require their own determination. A software check cannot assign an ASIL or establish the whole vehicle safety argument.
Examine the consequence of a small edit.
Illustrative example
A diagnostic debounce interval changes.
The edit changes how quickly a repeated fault is reported. Review the required timing, scheduling assumptions, startup state and behavior when input quality is uncertain. A unit test of the counter alone may not establish the integrated response time.
| Evidence layer | What to keep visible |
|---|---|
| Requirement | Allocated safety behavior and approved changes |
| Design and implementation | State, timing and interface assumptions |
| Verification | Relevant executions and analyzed properties |
| Assessment | Open gaps, exceptions and responsible decisions |
Keep a connected record for reviewers.
Proof can retain requirement relationships and links to implementation, hazards and verification evidence. The practical opportunity is to make a software change easier to assess and its missing support harder to overlook.
Use one real change to test that workflow with the functional-safety team. Tool confidence, required independence and broader assessment obligations need explicit treatment in the project; this page makes no qualification claim for Proof.
Try it on your software
Choose one change with a clear safety implication.
We can connect its evidence to the allocated requirement and your existing review process.
