Developing the Workshop

The workshop is written in reStructuredText (rst) and generated using Sphinx.

It is hosted on Read The Docs and currently uses the Material Design style developed by Google through a slightly custom version of the sphinx_materialdesign_theme package.

It uses the sphinxcontrib-session extension to properly highlight the example sessions and to allow copying only the session lines.

Other sphinx extensions which are used include;

• sphinxcontrib-hdl-diagrams to generate nice diagrams from Verilog examples.
• sphinx-wavedrom to generate nice waveform diagrams. sphinxcontrib-wavedrom?
• symbolator to generate block level diagrams from Verilog examples.
• sphinx_tabs to support tabs for different Linux / Windows / Mac OS X instructions.

Useful Resources for writing docs

• Sphinx RestructuredText Primer
• ReStructuredText directives
• Material Design Icons
