Wave Preview

The Hardware Timing Diagram tool loads the local WaveDrom runtime on demand and renders standard WaveDrom JSON into SVG waveforms in the browser. It is useful for hardware documentation, interface specs, debug notes, and I2C/SPI timing sketches.

Practical guide

Hardware Timing Diagram

Turn WaveDrom-style timing descriptions into readable bus diagrams for hardware documents and debug notes.

How to use

  1. Write or paste WaveDrom JSON into the source editor.
  2. Click render or use the sample to preview a waveform.
  3. Export SVG for documentation or PNG for quick issue comments and lab notes.
  4. Keep the JSON snippet with your design notes so the waveform can be regenerated later.

Common use cases

  • Documenting I2C, SPI, reset, interrupt, valid-ready, and simple protocol timing.
  • Sharing a waveform in firmware or hardware review without taking screenshots from a vendor tool.
  • Keeping timing examples in a markdown-based design note.

Privacy note

Timing JSON and exported images are generated locally. The waveform is not uploaded or logged by the site.
