Bring-up Signoff & Handoff

Section goal

Evidence-driven closure for silicon bring-up: milestone gate criteria, errata/workaround governance, respin decision economics, and final handoff to product and software teams.

How to study this section

1. Start with each topic hub and restate first-failure boundaries in your own words.

2. Use reports and debug pages to separate symptoms from root-cause classes.

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

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

Bring-up signoff is a governance system with explicit criteria, risk ownership, and production-safe handoff artifacts.

Concept diagram

SIGNOFF DECISION FLOW

milestones met -> risk review -> workaround viability -> release or respin decision

Metric graph

SIGNOFF READINESS

open unknowns            █████
mitigated known risks    ███████
release-ready packet     ██████

Metrics and artifacts to collect

• milestone gate attainment

• errata severity and mitigation status

• respin decision evidence ledger

• handoff packet completeness

Mini case study

A risky launch was avoided when signoff criteria exposed unresolved corner instability masked by nominal smoke passes.

Debug branches

• Convert each risk statement into one verification artifact.

• Evaluate workaround sustainability under scale.

• Document rollback triggers before release approval.

Senior review question

Ask: what is the first failing boundary, which artifact proves it, and who owns bounded closure?
