SIMULATION / SA-EDA-CTS-ROUTE-IR-002
CTS, routing, and IR-drop report handoff replay
CTS / route / IR handoff
A browser replay that aligns clock-tree timing, route completion and RC, power-grid pressure, checkpoint maturity, owner view, and replacement evidence without running a live flow or implying signoff.
EXPLORE
Start with the observable.
Use this page when the simulation is the primary artifact. The linked lesson explains the concept; the linked lab keeps the visual replay surface available.
- Filter clock, routing, power-grid, handoff-stage, review-role, and evidence-posture states before comparing any score.
- Read raw fixture metrics beside normalized skew, latency, congestion, completion, RC, IR, current-density, mismatch, and readiness fields.
- Use the gate to identify the owned report, aligned checkpoint, extraction, activity, or owner review still missing.
- Keep the boundary visible: independent fixture combinations are not a coupled implementation, closure result, ECO instruction, or signoff packet.
BROWSER INTERACTIVE LAB
Filter the saved CSV. Inspect matching replay rows.
No server solver is running here. The browser filters a precomputed table and redraws the plot locally.

Each metric is normalized independently for shape inspection. Vertical positions do not compare magnitude across metrics.

RUN CARD
Conditions before conclusions.
The browser filters a saved CSV. It does not execute or accept OpenROAD/OpenLane/OpenSTA/PDNSim/OpenRCX flows, designs, libraries, PDKs, reports, constraints, activity, or signoff data.
Primary knobs
- clock profile
- routing profile
- power profile
- handoff stage
- review role
- evidence posture
Saved outputs
- clock skew and insertion pressure
- setup/hold risk proxies
- route congestion and completion risk
- detour/via and extracted-RC pressure
- IR-drop and current-density pressure
- cross-report mismatch and consistency
- timing, power-integrity, and total handoff readiness
- decision gate and next safe check

How the number was made.
Methods are written for citation discipline: the extraction rule matters as much as the plotted value.
Select four representative states from each independently verified SA-LAY-007 clock, SA-LAY-008 route, and SA-LAY-009 power-grid matrix.
Keep this method attached when reusing the figure or metric.
Create a deterministic 4 x 4 x 4 x 4 x 4 x 4 report-handoff sweep while retaining the original selected metrics and source IDs.
Keep this method attached when reusing the figure or metric.
Compute bounded report-triage pressures, consistency, evidence coverage, role-weighted priority, readiness caps, decision gates, and next checks.
Keep this method attached when reusing the figure or metric.
Hash the source matrices, contracts, and both primary and independent QA records so the lineage survives cross-device handoff.
Keep this method attached when reusing the figure or metric.
LIMITS
What this page does not claim.
The MVP is useful because the limits are visible. These statements prevent a teaching simulation from being cited as silicon evidence.
No live OpenROAD, OpenLane, OpenSTA, TritonCTS, FastRoute, TritonRoute, PDNSim, OpenRCX, SPICE, PEX, or server-side EDA execution.
Carry this boundary into any derivative note, paper draft, or slide.
No uploaded design, netlist, constraint, timing, congestion, DRC, route, power, activity, DEF, GDS, LEF, Liberty, SDC, SPEF, or report parsing.
Carry this boundary into any derivative note, paper draft, or slide.
No PDK, standard-cell library, technology file, extraction rule, foundry rule deck, proprietary report body, or restricted design collateral is copied or redistributed.
Carry this boundary into any derivative note, paper draft, or slide.
The three source fixtures are independent PDK-free teaching experiments. Their Cartesian juxtaposition is a report-handoff rehearsal, not a coupled implementation run.
Carry this boundary into any derivative note, paper draft, or slide.
No row is timing closure, detailed-route completion, EM/IR signoff, ECO guidance, tapeout readiness, qualification, foundry acceptance, or product readiness.
Carry this boundary into any derivative note, paper draft, or slide.
Owned tool versions, design checkpoint, libraries, constraints, extraction, activity/current data, corners, report provenance, and accountable owner review are required for engineering reuse.
Carry this boundary into any derivative note, paper draft, or slide.
