Digital timing diagram editor with analog effects for specs and documentation.

FLAGSHIP PRODUCT

TimeGen™ 5

The timing diagram editor engineers have relied on since 2003 — available online, or fully installed on your own computer, with live click-and-drag waveform editing.

  • Zero syntax — interactive GUI, pure click & drag editing
  • Digital signal states — High-Z, weak drive, glitches, contention
  • Analog edge effects — ringing, RC curves, ramps, noise, voltage markers & rail labels
  • Vector exports (SVG & PDF) for crisp documentation
  • Direct Ctrl+C copy to Microsoft Word & FrameMaker
