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
  • Move input delta and offset sigma together to see why small-signal sensing becomes a yield question.
  • Read regeneration time and decision probability as separate outputs.
  • Compare this generic card with the SRAM sense-margin simulation.

RUN CARD

Conditions before conclusions.

This page replays saved sense-regeneration data and does not run a live latch, comparator, or SRAM peripheral simulation.

METHODS

How the number was made.

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

method

Decision probability uses a logistic curve around input differential minus an offset penalty.

Keep this method attached when reusing the figure or metric.

method

Regeneration time follows a log gain target divided by input differential.

Keep this method attached when reusing the figure or metric.

method

Fail-rate proxy is derived from one minus decision probability.

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

No transistor-level latch equations, Monte Carlo mismatch, kickback, metastability tail, or layout parasitic model.

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

non-claim

No SRAM, DRAM, ADC, comparator, or product yield claim is made.

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

non-claim

Use as a bridge to SPICE or measured offset distributions before citing design margins.

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

Seed sweep JSON records input delta, offset sigma, decision probability, time, and fail-rate rows.

evidence note

CSV export preserves the regeneration comparison table.

evidence note

Existing SRAM sense-margin page remains the SRAM-specific evidence layer.

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

No server-side live ngspice execution, uploads, accounts, payments, comments, newsletter signup, or job/event submissions are active on this page.
