2. What is WaveDrom?

WaveDrom is a simple, JSON-based language used to describe digital timing diagrams. It's widely used in electronics, embedded systems, and documentation to represent clock signals, data streams, control signals, and more. With WaveDrom, you can define signal transitions, timing relationships, and behavior across time in a readable and programmable way.

3. Supported WaveDrom Features

MassiveDiag Playground supports the full range of WaveDrom elements, including:

  • Clock and signal waveforms
  • Bus values and labels
  • Signal grouping
  • Phase delays
  • Control signals (e.g., req/ack)
  • Nested signal hierarchies

Whether you’re visualizing a simple waveform or a complex protocol, we’ve got you covered.

4. Example of a WaveDrom Diagram

WaveDrom Code

{
  "signal": [
    {"name": "clk", "wave": "P......."},
    {"name": "data", "wave": "x.345x.7"},
    {"name": "req", "wave": "01.0..1."},
    {"name": "ack", "wave": "0..1..0."}
  ]
}

5. Getting Started with WaveDrom

To begin creating WaveDrom diagrams with MassiveDiag:

  1. Write or generate your WaveDrom JSON code.
  2. Go to the MassiveDiag Playground.
  3. Paste your code or upload a file.
  4. Select the diagram type (auto-detected in most cases).
  5. Click Create Diagram and watch it render in real-time.

6. How to Use WaveDrom in MassiveDiag Playground

Here's how the workflow looks:

  1. Generate Code – Use AI or write your own WaveDrom code.
{
  "signal": [
    {"name": "clk", "wave": "P......."},
    {"name": "data", "wave": "x.345x.7"},
    {"name": "req", "wave": "01.0..1."},
    {"name": "ack", "wave": "0..1..0."}
  ]
}

  1. Upload to Playground – Paste or drag-and-drop your code.

    Step 2

  2. Auto-Detect Diagram Type – Or manually set it if needed.

    Step 3

  3. Create Diagram – Let the platform process the input.
