OpenTitan

This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository.

Documentation

The project contains comprehensive documentation of all IPs and tools. You can either access it online or build it locally by following the steps below.

  1. Ensure that you have the required Python modules installed (to be executed in the repository root):
$ sudo apt install python3 python3-pip
$ pip3 install --user -r python-requirements.txt
  1. Execute the build script:
$ ./util/build_docs.py --preview

This compiles the documentation into ./opentitan-docs and starts a local server, which allows you to access the documentation at http://127.0.0.1:5500.
