Use these drills after completing all topics in Low Power Verification. Answer with state transition, policy object, owner, artifact, fix, and regression evidence.
[INT][LP][LOW-POWER-VERIFICATION]
Q: What is the difference between state coverage and transition coverage?
A:
State coverage proves residency; transition coverage proves legal movement and sequencing correctness between states.
FOLLOW-UP TRAP: Claiming closure with state-only bins.[INT][LP][LOW-POWER-VERIFICATION]
Q: Where do formal LP checks add unique value?
A:
Formal exhaustively proves classes of connectivity/control bugs that simulation may miss due to stimulus limits.
FOLLOW-UP TRAP: Replacing simulation with formal or vice versa.[INT][LP][LOW-POWER-VERIFICATION]
Q: How should LP debug be structured during regressions?
A:
State timeline first, then policy binding, then implementation evidence, then focused reproducer and full matrix rerun.
FOLLOW-UP TRAP: Jumping to waveform-only debugging without policy context.STATE -> POLICY -> SEQUENCE -> IMPLEMENTATION -> REGRESSIONVERIFY LOOP
transition matrix -> simulation + formal -> coverage -> closureState transition context must accompany every low-power metric claim.
Intent changes require simulation, formal, and implementation re-validation.
Comparing results from mismatched UPF revisions.
Assuming static checks replace transition validation.

Use this pack to rehearse low-power closure on low-power/low-power-verification/low-power-verification-tricky-qa: transition framing, policy ownership, implementation evidence, and release confidence.
State transition explicitly named with legal source/target states.
Crossing and domain ownership are mapped and agreed.
Policy controls are traced to always-on source logic.
Waveform bookmarks align controls with state timestamps.
Which policy object is first to deviate from intent?
Which owner can apply the smallest reversible fix?
What regression matrix proves no collateral damage?
Which waiver conditions would still block release?
