Reset-Domain Integration Debug: Reports & Metrics

Reports and metrics

Reports & Metrics for Reset-Domain Integration Debug focuses on reset-domain escape count, debug turnaround for boot hangs. The goal is to map symptoms to boundary contracts, owner actions, and regression-proof closure.

The job of a report is to convert reset-domain escape count, debug turnaround for boot hangs into a closure decision. One summary number is never enough without baseline, owner, and boundary context.

Debug the high-severity tail first; averages hide escape risk.

• Track reset-domain escape count, debug turnaround for boot hangs by domain and owner boundary.

• Store baseline manifest beside every metric snapshot.

• Report both immediate fix result and full regression result.

• Explicitly call out residual risk and ownership.

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.
