LESSON PACKET / SA-EDA-CTS-ROUTE-IR-002

A green report is not a cross-domain closure claim.
EDA / Layout

Clock-tree, route, extracted-RC, and power-integrity evidence must share checkpoint, corner, tool, input, and owner context. This replay keeps those handoff questions attached to every row.

EVIDENCE SEQUENCE

What the learner should inspect first.

This surface connects the daily-scan source signal to an original SemiAgora simulation object without copying source text, code, figures, PDK files, or process recipes.

01

Choose clock, routing, and power-grid fixture states before reading a combined readiness score.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
02

Align post-CTS, global-route, detailed-route, or extraction stage with the timing, routing, power-integrity, or integration owner view.

Open the run card to inspect the saved rows, methods, limits, and export files behind this step.

Inspect run card ->
03

Use the gate to request the missing owned report, constraint, extraction, activity, checkpoint alignment, or owner review.

METHODS

Precomputed model contract.

The goal is useful study scaffolding and paper-planning discipline, not calibrated production evidence.

method

Selected metrics come from independently verified PDK-free SA-LAY-007, SA-LAY-008, and SA-LAY-009 fixtures.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

method

The browser filters a deterministic Cartesian report-handoff rehearsal and preserves fixture/contract/QA hashes.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

method

No external report body, PDK, library, design, rule deck, constraint, or signoff collateral is copied or parsed.

The simulation object keeps the same statement beside downloadable JSON and CSV evidence.

LIMITS

Useful, but deliberately bounded.

No account, upload, payment, comment, newsletter, live solver, facility workflow, or product-release surface is enabled.

non-claim

No live OpenROAD, OpenLane, OpenSTA, TritonCTS, FastRoute, TritonRoute, PDNSim, OpenRCX, PEX, or uploaded report processing.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

non-claim

Independent fixture states are juxtaposed, not co-simulated or correlated to one implementation.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

non-claim

Real closure needs owned same-checkpoint reports, libraries, constraints, extraction, activity/current data, corners, tool versions, and accountable owner approval.

Keep this boundary attached when reusing the card for lesson writing, figure planning, or research notes.

SOURCE ANCHOR

Link-only public source spine.

SemiAgora uses the source as a signal and citation anchor, then writes original summaries and original toy data with explicit limitations.
