SIMULATION / SA-EDA-OPENROAD-STARTER-002
OpenROAD starter flow QoR parser
OpenROAD Starter
Filter tiny RTL seeds, utilization, target clock, and routing effort to inspect WNS, TNS, congestion, marker-count, area, wirelength, and power proxy report fields before a real rights-cleared 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.
- Start with inverter chain, 8-bit counter, and SRAM peripheral proxy seeds rather than a full chip.
- Filter utilization, target clock, and routing effort to see why WNS/TNS, congestion, DRC markers, and power move together.
- Use the parser fields as a checklist for a future GitHub Actions package that runs real open tools on rights-cleared inputs.
- Treat the SRAM peripheral proxy as implementation literacy, not as a memory compiler or signoff SRAM macro.
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 report-parser rows and redraws local plots. It does not run OpenROAD, OpenLane, OpenSTA, SPICE, TCAD, or a server-side compile flow.
Primary knobs
- design seed: inverter_chain, counter_8bit, sram_peripheral_proxy
- utilization_pct: 35, 50, 65, 78
- target_clock_ns: 1.0, 1.5, 2.0, 3.0
- routing_effort: low, balanced, high
Saved outputs
- cell count, buffer count, floorplan area, placed area
- route wirelength, critical path, WNS, TNS, failing paths
- congestion risk, DRC marker count, leakage power, dynamic power
- report parse confidence and debug bucket

How the number was made.
Methods are written for citation discipline: the extraction rule matters as much as the plotted value.
Generate a deterministic factorial sweep over tiny design seed, utilization, target clock, and routing effort.
Keep this method attached when reusing the figure or metric.
Map each row into QoR-style report fields that learners can parse before running real OpenROAD or OpenLane locally.
Keep this method attached when reusing the figure or metric.
Represent the SRAM peripheral as public structural logic only; no private SRAM macro, memory compiler, PDK, or foundry deck is used.
Keep this method attached when reusing the figure or metric.
Keep sample reports and parser-field contracts ready for a future GitHub Action that can replace proxy rows with rights-cleared real reports.
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.
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.
Values are original educational proxies, not OpenROAD, OpenLane, OpenSTA, silicon, tapeout, product, or signoff results.
Carry this boundary into any derivative note, paper draft, or slide.
No user-supplied design files, PDK files, Liberty, LEF/DEF, SPEF, SDC, private reports, account, payment, comment, newsletter, or job/event workflow is enabled.
Carry this boundary into any derivative note, paper draft, or slide.
The SRAM peripheral proxy excludes real compiler macros, extracted parasitics, variation, EMIR, DFM, and closure authority.
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.
Generator, verifier, CSV, summary, sample reports, web model, and backlog are stored under OPENROAD_STARTER_FLOW_2026-08-16.

Measured replacement slots are named for real ORFS/OpenLane logs, OpenSTA reports, version manifests, route markers, congestion reports, and power reports.
