Power Intent Overview for Verification: Inputs and Outputs

Inputs and outputs contract

Inputs and Outputs for Power Intent Overview for Verification is anchored on illegal transition rate, corruption incidence, and deterministic replay quality under low-power scenarios. Convert observations into mechanism-backed and owner-bound actions.

INPUTS
  - power-mode sequence and ownership context
  - seed, order, and configuration metadata
  - intent assumptions for transitions and crossings
  - assertion and coverage expectation envelope

OUTPUTS
  - evidence-backed failure classification
  - owner-signed mitigation proposal
  - validation matrix and rollback triggers
  - release recommendation

Low-power verification deep dive

LPV foundations are strongest when power intent, simulation semantics, and ownership boundaries are explicit from day one.

Metrics and artifacts to collect

• intent-to-RTL alignment checklist

• power-mode onboarding packet

• ownership map for controls and checks

• first-failure boundary report

Mini case study

A project reduced LPV bring-up churn after requiring explicit domain-control ownership and transition evidence in every review.

Debug branches

• Prove setup correctness before chasing downstream symptoms.

• Record domain ownership for each control and checker.

• Distinguish intent mismatch from RTL implementation bugs.

Senior review question

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

Key takeaways

• Tie each LPV claim to a concrete transition boundary and one proving artifact.

• Prefer minimal reversible fixes with explicit owner and rollback criteria.

Common pitfalls

• Treating power-aware failures as random before boundary classification.

• Waiving X-prop failures before proving impact and root cause.

• Declaring closure without deterministic replay across key modes.

Handoff explanation

Inputs should include mode sequence, domain status, and control ownership context.

Outputs should include deterministic reproducer and acceptance boundaries.
