Global Address Map Planning: Review Checklist

Review Checklist for Global Address Map Planning.

Review checklist

Review Checklist for Global Address Map Planning focuses on decode conflicts, remap churn, software breakage from map changes. The goal is to map symptoms to boundary contracts, owner actions, and regression-proof closure.

  • Baseline manifest and revision are explicit.

  • Boundary contracts for this topic are current and approved.

  • Ownership map covers all open issues.

  • Focused and full regression evidence both exist.

  • Residual risks are either closed or bounded via waiver policy.

  • Owners signed: SoC architect, firmware architect, security owner.

OWNERSHIP MAP — Global Address Map Planning

artifact             owner
-----------------    -----------------
primary owner     SoC architect
co-owner          firmware architect
review owner      security owner

No top-level issue should remain ownerless beyond one review cycle.

SoC deep dive

Address, interrupt, and IO contracts are where hardware/software alignment is won or lost.

Reports and artifacts

  • address decode audit

  • interrupt latency report

  • IO bring-up checklist

  • boot contract review

Mini case study

A map alias issue caused sporadic peripheral misconfiguration despite clean block-level tests.

Debug branches

  • Freeze address map baseline

  • Audit reset defaults

  • Validate firmware assumptions

Senior review question

Ask: what baseline, owner, and artifact prove this topic is truly closed?

Key takeaways

  • State baseline manifest and owner with every closure metric.

  • Run cross-domain regression after every top-level fix.

Common pitfalls

  • Comparing results across different manifests.

  • Unowned issues slipping through review cycles.

  • Waiving risks without expiry and validation plan.

Principal SoC review addendum

A stable address map aligns hardware decode, virtualization windows, security regions, and firmware assumptions across the product lifecycle.

Metric: decode conflicts, remap churn, software breakage from map changes
