Intended primarily for documentation purposes, electronic hardware designers can use Waveme to draw a timing diagram,
and then export it to an image file (BMP, PNG, SVG or TIFF) or a PDF document.
Waveme can be used to draw waveforms, gaps, arrows, labels, value-lines and time axis (see attached images).
Both, digital and analog signals can be drawn.
Highly customizable, with a wealth of keyboard shortcuts.
Waveme is distributed as a portable 64-bit single-file executable - it doesn't require installation.
Please note that because it is an unsigned executable file, a browser will issue you a warning, and it might be flagged by antivirus programs.
