Introduction
WaveDrom is a Free and Open Source online digital timing diagram (waveform) rendering engine that uses javascript, HTML5 and SVG to convert a WaveJSON input text description into SVG vector graphics.
WaveJSON is an application of the JSON format. The purpose of WaveJSON is to provide a compact exchange format for digital timing diagrams utilized by digital HW / IC engineers.
The engine is using WaveDromSkin skin mechanism to render a complete picture.

HTML pages
There are three steps to insert WaveDrom diagrams directly into your page:
- Put the following line into your HTML page
<header>or<body>:
<script src="http://wavedrom.com/skins/default.js" type="text/javascript"></script>
<script src="http://wavedrom.com/wavedrom.min.js" type="text/javascript"></script>
or from a CDN:
<script src="https://cdnjs.cloudflare.com/ajax/libs/wavedrom/2.3.2/skins/default.js" type="text/javascript"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/wavedrom/2.3.2/wavedrom.min.js" type="text/javascript"></script>
- Set the
onloadevent for the HTML body.
<body onload="WaveDrom.ProcessAll()">
- Insert WaveJSON source inside HTML
<body>wrapped with the<script>tag:
<script type="WaveDrom">
{ signal : [
{ name: "clk", wave: "p......" },
{ name: "bus", wave: "x.34.5x", data: "head body tail" },
{ name: "wire", wave: "0.1..0." },
]}
</script>
The script will find all <script type="WaveDrom"> instances and insert a timing diagram at that point.
