#  Validation matrix

| Area            | Minimum validation                                                                                  |
| --------------- | --------------------------------------------------------------------------------------------------- |
| Boot            | Image load, reset-vector programming, stable first instruction fetch, repeatable reboot.            |
| Interrupts      | Correct routing, clean ISR entry and exit, and spurious interrupt checks.                           |
| UART            | Console behavior, receive handling, and any enabled flow-control behavior.                          |
| I2C             | Read and write behavior, NACK handling, repeated-start behavior, timeout detection, and recovery    |
| I3C             | Addressing policy, transfer completion, and supported compatibilitypath behavior.                   |
| QUP plus GPI    | Descriptor queueing, completion IRQs, ring reset or drain, timeout, and abort behavior.             |
| Power           | D0, D1, D2, and platform-specific D3 transition checks, wakesource correctness, and no lost context |
| Resource voting | Correct assertion and release timing for clocks, rails, and paths.                                  |
| Diagnostics     | Crash logs, trace, and fault artifacts usable for root-cause analysis                               |
