SIMULATION / SA-EDA-FLOORPLAN-001
Floorplan congestion, IR-drop, and clock-spine replay
Floorplan reports
A browser CSV lab for physical-design report literacy: compare utilization, aspect ratio, macro channel pressure, PDN strategy, clock topology, and report stage against placement overflow, RUDY-style congestion, global-route overflow, IR-drop risk, current-density risk, skew, insertion delay, timing-slack risk, and the next safe evidence check.
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 utilization, macro strategy, PDN strategy, clock topology, and report stage before reading any single congestion or timing-risk number.
- Compare RUDY-style routability, global-route overflow, IR-drop risk, current-density risk, skew risk, insertion-delay proxy, and timing-slack risk together.
- Use the decision gate to choose whether the next review belongs to floorplan sizing, macro channels, PDN/IR-drop, CTS, global route, or owned-report evidence.
- Keep the no-upload/no-live-flow boundary visible so report literacy does not become a public signoff service.
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.

RUN CARD
Conditions before conclusions.
The browser filters saved CSV rows. It does not run OpenROAD/OpenLane/OpenSTA, parse uploaded reports, accept DEF/GDS/SPEF/SDC/Liberty files, redistribute PDK collateral, or make signoff/tapeout claims.

How the number was made.
Methods are written for citation discipline: the extraction rule matters as much as the plotted value.
Generate a Cartesian synthetic sweep across floorplan profile, macro strategy, utilization, PDN strategy, clock topology, and report stage.
Keep this method attached when reusing the figure or metric.
Normalize public OpenROAD/OpenLane vocabulary into proxy scores for placement overflow, RUDY-style congestion, routing overflow, PDN/IR-drop, CTS, and timing-risk review.
Keep this method attached when reusing the figure or metric.
Apply decision gates that route the learner to floorplan sizing, macro channels, PDN/IR-drop, CTS, global-routing, or owned-report checks before any claim is reused.
Keep this method attached when reusing the figure or metric.
Store CSV, typed JSON, model card, and source notes under the public data folder and experiment folder.

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 DEF, GDS, LEF, SPEF, SDC, Liberty, routed database, extracted parasitics, PDK, rule deck, timing library, or proprietary report is accepted, copied, or redistributed.
Carry this boundary into any derivative note, paper draft, or slide.
No live server OpenROAD, OpenLane, OpenSTA, Magic, Netgen, PEX, field-solver, SPICE, uploaded-design, account, payment, comment, newsletter signup, job/event submission, or public service intake is active.
Carry this boundary into any derivative note, paper draft, or slide.
No routing guidance, ECO recommendation, timing closure, PDN signoff, DRC/LVS signoff, tapeout readiness, foundry qualification, or product claim is made.
Carry this boundary into any derivative note, paper draft, or slide.
Rows are normalized synthetic teaching proxies and require rights-clean owned reports before stronger engineering reuse.
Carry this boundary into any derivative note, paper draft, or slide.
