SIMULATION / SA-EDA-OPENROAD-QOR-001

OpenROAD starter QoR resampling interactive lab
OpenROAD QoR

Filter tiny design, utilization, clock target, and buffering strategy to inspect WNS, congestion, route-risk, area, and power teaching proxies before a real reproducible flow.

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.

guided exploration
  • Compare utilization, timing target, and buffering before running a real open-source flow.
  • Read WNS, congestion, route-violation proxy, and power proxies as coupled QoR terms.
  • Use this as the public preview before a rights-reviewed GitHub reproducible OpenROAD package.

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 saved QoR surrogate rows. It does not run OpenROAD/OpenLane on the server, accept uploaded RTL, publish a signoff report, or create a tapeout-ready flow.

METHODS

How the number was made.

Methods are written for citation discipline: the extraction rule matters as much as the plotted value.

method

Area, wirelength, buffer count, timing, congestion, and power are generated by a deterministic teaching surrogate.

Keep this method attached when reusing the figure or metric.

method

WNS proxy is computed as clock target minus the synthetic critical-path proxy.

Keep this method attached when reusing the figure or metric.

method

Route-violation proxy combines congestion and negative-slack pressure to teach report triage before real tool logs exist.

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.

non-claim

Browser-side filtering and nearest-row replay only; no live server solver or EDA flow is active.

Carry this boundary into any derivative note, paper draft, or slide.

non-claim

This is not OpenROAD output and does not ingest RTL, Liberty, LEF/DEF, SPEF, SDC, or a PDK.

Carry this boundary into any derivative note, paper draft, or slide.

non-claim

No uploaded design, signoff timing, routing qualification, tapeout, or product release claim is supported.

Carry this boundary into any derivative note, paper draft, or slide.

EVIDENCE

Trace the claim back to artifacts.

The evidence route remains the catalog-level browser; this page is the simulation-level reading card.

evidence note

The CSV preserves every tiny-design, utilization, clock, buffer-strategy, and QoR-proxy row used by the browser lab.

SA-EDA-OPENROAD-QOR-001

evidence note

The source links identify the intended future OpenROAD/OpenLane reproduction path without copying tool code into the page.

SA-EDA-OPENROAD-QOR-001

evidence note

The replay is a public teaching surface before a separate real-tool experiment is preserved.

Source spine

These links anchor the public teaching model. They do not convert the replay into a qualified process recipe or signoff result.
