Interview Drills for UPF Consistency Audit focuses on cross-tool mismatch count, stale UPF object references, and signoff waiver backlog. The goal is to link observed behavior to power-intent mechanism, ownership, and release risk.
PROMPT
You see cross-tool mismatch count, stale UPF object references, and signoff waiver backlog on UPF Consistency Audit. Walk through root cause and release decision.
STRONG ANSWER
1. Names failing state transition and domains.
2. Explains Consistency audits compare intent interpretation across RTL, synthesis, PD, simulation, and formal views to prevent semantic drift.
3. Requests multi-tool consistency dashboard, mismatch diff, and closure memo.
4. Proposes bounded fix and regression matrix.
WEAK ANSWER
Jumps to generic UPF edits without transition timeline, ownership, or signoff evidence.CONSISTENCY MATRIX
view status key mismatch?
RTL sim pass -
synthesis pass retention naming
PD implementation fail missing AON tap
formal LP pass -
Signoff requires semantic parity across views.ROOT-CAUSE TREE — UPF Consistency Audit

Ask: what transition evidence proves this topic is closed, and which owner signs it?
State 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.
Shipping with aged waivers and unclear ownership.
Use this pack to rehearse low-power closure on low-power/upf-implementation-flow/upf-consistency-audit/interview: 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?
