Trace and Debug Modules: Silicon PPA Impact
Silicon PPA Impact for Trace and Debug Modules.
Silicon PPA impact
Silicon PPA Impact for Trace and Debug Modules is anchored on Average time-to-root-cause for failing regressions using trace capture and debug trigger workflows.. 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.
