About this repository

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


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

command$ ./util/ --preview

This compiles the documentation into ./build/docs and starts a localserver, which allows you to access the documentation athttp://
