Illustrative first-order example. Checks are editable requirements, not design standards. The broader topic may require additional equations, data, and validation.

Formula and units

This example uses the following equations. Input names and units match the editable source above.

delay
delay = samplePeriod*stableSamples [ms]

Assumptions and limits

Consecutive stable-sample debounce delay; bounce duration supplied.

The requirement checks use the limits written in this example. Passing a check does not establish that the model covers every load, material behavior, or operating condition in a real design.

Take it further with your agent

Napkin keeps the inputs, equations, checks and assumptions together in one study. Your agent sets it up; you change the numbers.

Try with Claude ↗

codex 'Use Napkin (https://napkin.engineering/mcp, or the local Napkin plugin) to build a study: Switch debounce timing. Inputs: bounce trace/model; sampling; debounce rule. Outputs: accepted edges; latency; missed-pulse conditions. Model scope: Declared clock, peripheral and execution assumptions. Read napkin_capabilities and the current snapshot. Ask me for the values that matter, label assumptions with units, author .napkin source, validate it and apply it with napkin_source using the current revision, then open the study. Add checks for the limits I supply. Keep unsupported analyses explicit.'

The broader study

The topic brief below describes the broader scope. The worked example above states the particular calculation it implements.

  • Inputs: bounce trace/model, sampling, debounce rule
  • Outputs: accepted edges, latency, missed-pulse conditions
  • Modes: calculate, compare, sweep
  • Drawing: Timing diagram or event simulation
