Sphinx Extension which generates various types of diagrams from Verilog code.

sphinxcontrib-verilog-diagrams is a Sphinx extension to make it easier to write nice documentation from Verilog files. It primarily uses Yosys to do the Verilog reading.

Check out the documentation for examples.

Or,

python3 -m pip install sphinxcontrib-verilog-diagrams

]

Usage

verilog-diagram

The verilog-diagram RST directive can be used to generate a diagram from Verilog code and include it in your documentation. Check out the examples to see how to use it.

.. verilog-diagram:: file.v
   :type: XXXXX
   :module: XXXX
   :flatten:

Options

:type: - Verilog Diagram Types;

  • yosys-blackbox - Netlist rendered by Yosys.

  • yosys-aig - Verilog file run through aigmap before image is generated directly in Yosys.

  • netlistsvg - Render output with netlistsvg

:module: - Which module to diagram.

:flatten: - Use the Yosys flatten command before generating the image.

Example

Here is a diagram of a 4-bit carry chain.

no-license

This extension also provides the no-license directive which can be used to include code blocks from a file, but omitting the license header at the top of the file. It behaves like the literalinclude directive, but the lines option is overridden to only show the lines after the license header.

.. no-license:: verilog/dff.v
   :language: verilog
   :linenos:
   :caption: verilog/dff.v

Example

Here is a comparison between the literalinclude and no-license directives.

.. literalinclude:: verilog/dff.v
   :language: verilog
   :caption: verilog/dff.v
