UPF Signoff Dashboard: Worked Example

Worked Example for UPF Signoff Dashboard.

Worked example

Worked Example for UPF Signoff Dashboard focuses on open LP violations, waiver aging, and closure trend by subsystem. The goal is to link observed behavior to power-intent mechanism, ownership, and release risk.

A nightly regression flags open LP violations, waiver aging, and closure trend by subsystem. The correct approach is to freeze transition context, verify policy intent on the failing crossing, and then apply a minimal fix with full LP regression discipline.

STATE TRANSITIONS — UPF Signoff Dashboard

ON  --save-->  RETENTION  --off-->  OFF
 ^               |                    |
 |               +----restore<--------+
 +--------------------power_up--------+

Guard checks:
  - isolation asserted before OFF
  - restore before functional traffic
  - reset policy consistent with retained state

Reports and artifacts

domain grid report
dynamic IR analysis
LP signoff dashboard
handoff owner matrix

Mini case study

Dynamic IR during wake-up, not static IR, was the true blocker for release.

Debug branches

Inspect transition waveforms
Check PMU schedule alignment
Escalate aged waivers

Senior review question

Ask: what transition evidence proves this topic is closed, and which owner signs it?

Key takeaways

State transition context must accompany every low-power metric claim.
Intent changes require simulation, formal, and implementation re-validation.

Common pitfalls

Comparing results from mismatched UPF revisions.
Assuming static checks replace transition validation.
Shipping with aged waivers and unclear ownership.
