What is the minimum IP handoff quality bar?

[INT][SOC][IP-INTEGRATION]

Q: What is the minimum IP handoff quality bar?

A:
Versioned RTL/netlist, constraints, abstracts, verification status, and known limitations with owner signoff.

FOLLOW-UP TRAP: Shipping only RTL and patching collateral later.

How does manifest locking reduce integration churn?

[INT][SOC][IP-INTEGRATION]

Q: How does manifest locking reduce integration churn?

A:
It prevents silent version skew so every debug outcome is tied to reproducible inputs.

FOLLOW-UP TRAP: Using latest-of-everything in nightly builds.

When should bring-up issues escalate beyond block owners?

[INT][SOC][IP-INTEGRATION]

Q: When should bring-up issues escalate beyond block owners?

A:
When symptoms cross owner boundaries or baseline drift blocks deterministic root-cause isolation.

FOLLOW-UP TRAP: Keeping cross-domain bugs siloed in one team.

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.
