Coverage-Driven Verification: Silicon PPA Impact
Silicon PPA Impact for Coverage-Driven Verification.
Silicon PPA impact
Silicon PPA Impact for Coverage-Driven Verification is anchored on Risk-weighted closure across functional coverage, assertion coverage, code coverage, and bug escape trend.. Convert observations into mechanism-backed decisions with explicit ownership.
Frequency gains that increase bubbles may lose net throughput.
Area growth from extension logic must justify workload value.
Power and thermal stability are release gates, not secondary metrics.
