Bump Map & Escape Planning: Review Checklist

Review Checklist for Bump Map & Escape Planning.

Review checklist

Review Checklist for Bump Map & Escape Planning focuses on bump congestion, reroute churn, escape DRC violations. 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: package owner, top-level PD owner, power integrity owner.

OWNERSHIP MAP — Bump Map & Escape Planning

artifact             owner
-----------------    -----------------
primary owner     package owner
co-owner          top-level PD owner
review owner      power integrity owner

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

SoC deep dive

Package assumptions must be treated as first-class chip constraints.

Reports and artifacts

bump map revision log
SI/PI margin report
IO co-design checklist
package bring-up failures

Mini case study

Link degradation on product board came from package routing assumptions not reflected in pre-silicon model.

Debug branches

Compare package model versions
Audit lane mapping
Correlate SI/PI margins to failures

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

Bump maps and escape strategy determine routability, IR quality, and package feasibility before final pad-ring freeze.

Metric: bump congestion, reroute churn, escape DRC violations
