Reset Distribution & Sequencing: Review Checklist

Review checklist

Review Checklist for Reset Distribution & Sequencing focuses on reset release violations, bring-up reset bug rate. 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: reset architect, firmware owner, verification owner.

Signoff ownership

OWNERSHIP MAP — Reset Distribution & Sequencing

artifact             owner
-----------------    -----------------
primary owner     reset architect
co-owner          firmware owner
review owner      verification owner

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

SoC deep dive

Clock/reset assumptions must be globally consistent across functional and test modes.

Reports and artifacts

• clock architecture report

• reset release timing

• mode matrix

• boot trace summary

Mini case study

Intermittent boot hang traced to one domain releasing reset before dependent clock was stable.

Debug branches

• Check mode-specific constraints

• Trace reset dependencies

• Correlate firmware sequencing

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

Reset trees and release sequencing must match power/clock dependencies to prevent metastability, deadlock, and phantom boot failures.
