Low Power Assertions & Coverage

Section goal

Assertion-driven low-power verification and coverage closure: writing UPF-aware properties, building a power coverage model for states and transitions, deploying focused low-power checkers, and converging signoff evidence with risk-weighted closure.

How to study this section

1. Start with each topic hub and restate boundary mechanism in your own words.

2. Use reports and debug pages to classify first failing low-power phase.

3. Practice worked examples and interview drills under fixed metadata.

4. Close with checklist and execution impact before signoff claims.

2. power-coverage-model/ - Building a Power Coverage Model

Assertions and coverage translate LPV intent into measurable closure confidence and prioritized risk reduction.

Metrics and artifacts to collect

• assertion failure taxonomy

• mode-transition coverage heatmap

• crossing risk coverage report

• coverage closure readiness packet

Mini case study

Coverage closure accelerated once failures were grouped by transition risk class instead of tool report order.

Debug branches

• Prioritize coverage by product-risk scenarios.

• Separate actionable assertion classes from setup noise.

• Use closure criteria with explicit waiver governance.

Senior review question

Ask: what exact low-power transition boundary failed first, and which artifact proves the closure claim reproducibly?
