    What this topic teaches

    ML Timing & Power Prediction turns AI concepts into VLSI-ready engineering decisions. Surrogate models approximate STA and power analyses to accelerate early exploration and prioritize full signoff runs. The practical challenge is proving value with reproducible evidence, bounded risk, and explicit ownership.

    The senior-engineer question

    When timing/power estimation error, scenario ranking fidelity, and iteration savings moves, can you identify the failing layer, the mechanism, the artifact, and the owner who can close risk with a measurable fix?

    Evidence to collect

    • Primary metric: timing/power estimation error, scenario ranking fidelity, and iteration savings.

    • Primary artifact: prediction-vs-signoff scatter plot, error report, and triage recommendation list.

    • Owners to bring into review: STA owner, power signoff owner, EDA-ML engineer.

    • One workload slice where behavior regressed and one where it held.

    • One profile view that separates model issue from runtime/hardware issue.

    Subpages in this topic

    Each topic is taught across mechanism, inputs/outputs, reports, debug, worked example, pitfalls, interview, checklist, theory, design space, expanded case study, walkthrough, comparison matrix, software view, and silicon impact.

    Key takeaways

    • Always map ML metrics to engineering decisions and release risk.

    • Separate data/model issues from hardware/runtime bottlenecks before fixing.

    • Use reproducible artifacts and owner signoff for every rollout decision.

    Common pitfalls

    • Benchmark wins with no signoff correlation.

    • Ignoring calibration and drift when deploying quantized models.

    • Shipping without a rollback and ownership matrix.

    AI-VLSI deep dive

    EDA ML must prove signoff-correlated value with bounded risk and clear ownership.

    Reports and artifacts

    • correlation-to-signoff

    • runtime savings dashboard

    • false-prediction audit

    • fallback decision log

    Mini case study

    A model improved placement runtime, but confidence gating avoided a high-cost false optimization suggestion.

    Debug branches

    • Tie model output to signoff artifact

    • Audit confidence calibration

    • Preserve deterministic fallback

    Senior review question

    Ask: what evidence connects this ML claim to a concrete VLSI workflow decision and owner signoff?

    Key takeaways

    • Every AI claim should map to a measurable engineering outcome.

    • Validate both model quality and hardware/runtime feasibility before adoption.

    Common pitfalls

    • Optimizing benchmark metrics that do not correlate with signoff goals.

    • Ignoring data drift and calibration after deployment.

    • Shipping ML workflows without clear rollback ownership.
