SIMULATION / SA-EDA-STA-001
STA Liberty path slack replay
STA Slack
Replay VDD, temperature, load, and path depth to connect Liberty-style delay terms with setup slack, hold slack, and timing-report criticality.
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.
- Read timing as a path condition, not a single delay number.
- Keep setup and hold visible together before trusting a timing-report headline.
- Use this page before moving to a future OpenSTA reproduction package.
RUN CARD
Conditions before conclusions.
This page replays saved STA Slack rows and does not run a live solver, upload workflow, proprietary model, process recipe, or signoff flow.
Primary knobs
- VDD
- Ambient temperature
- Load capacitance
- Path stages
Saved outputs
- Cell delay
- wire delay
- arrival time
- setup slack
- hold slack

How the number was made.
Methods are written for citation discipline: the extraction rule matters as much as the plotted value.
Cell delay grows with voltage penalty, temperature factor, stage count, and load.
Keep this method attached when reusing the figure or metric.
Wire delay grows with stage count, load, and a small temperature factor.
Keep this method attached when reusing the figure or metric.
Setup and hold slack are computed from fixed educational clock and uncertainty terms.
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.
This is not OpenSTA output and does not ingest Liberty, SDC, SPEF, SDF, VCD, SAIF, or a gate-level netlist.
Carry this boundary into any derivative note, paper draft, or slide.
No signoff timing, PDK timing model, or arbitrary uploaded design is supported.
Carry this boundary into any derivative note, paper draft, or slide.
Use this page to teach report vocabulary before rights-reviewed OpenSTA artifacts are bundled.
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.
The JSON export stores all PVT/load/path-depth rows and slack bands.
SA-EDA-STA-001
The CSV export can become a timing worksheet for setup, hold, and critical-path reasoning.
SA-EDA-STA-001
The source spine points to OpenSTA and public timing-analysis tutorials without running them on the site.

These links anchor the public teaching model. They do not convert the replay into a qualified process recipe or signoff result.
Public execution boundary
No server-side live ngspice execution, uploads, accounts, payments, comments, newsletter signup, or job/event submissions are active on this page.
