EDITOR | TUTORIAL

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.

Web usage

WaveDrom timing diagrams can be embedded into the web pages, blogs, and wikis to be rendered by the most of modern browsers:

alt text 4+ 10+ 5.1+ 12+ 11

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/1.9.2/skins/default.js" type="text/javascript"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/wavedrom/1.9.2/wavedrom.min.js" type="text/javascript"></script>

Set the onload event 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.
