IP Handoff Readiness: Comparison Matrix
Comparison Matrix for IP Handoff Readiness.
Comparison matrix
Strict collateral governance trades initial overhead for fewer escapes.
+------------------+----------------+----------------+----------------+
| Approach | Strength | Weakness | Best when |
+------------------+----------------+----------------+----------------+
| Strict | predictable | slower early | new program |
| Balanced | practical | needs rigor | stable teams |
| Aggressive | fast | escape risk | late schedule |
| Re-architect | durable | expensive | recurring failures |
+------------------+----------------+----------------+----------------+When to choose each approach
Pick the approach based on residual silicon risk, not only schedule pressure.
Review traps
Policy-only arguments without artifact evidence
Unbounded waivers
Evidence comparison
INTEGRATION EVIDENCE MATRIX — IP Handoff Readiness
+-------------------+------------------------+--------------------------+-------------------------+
| Evidence | Tells you | Does not prove | Next action |
+-------------------+------------------------+--------------------------+-------------------------+
| Manifest diff | baseline changed | root cause itself | isolate first delta |
| Domain trace | where behavior diverged| ownership accountability | map to contract owner |
| Signoff dashboard | closure posture | reproducibility quality | verify source artifacts |
| Bring-up logs | software-visible symptom| physical/timing cause | correlate with HW trace |
| Waiver register | accepted residual risk | technical closure | review expiry criteria |

Mini case study
Most top-level debug time was spent on collateral drift, not RTL defects.
Debug branches
Validate handoff checklist
Lock manifest hashes
Correlate issue to owner boundary
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
IP handoff must include validated RTL/netlist, constraints, CDC assumptions, and documented limitations to avoid top-level rework.
