OpenTitan

Introduction to OpenTitan

OpenTitan is an open source secure silicon ecosystem producing both silicon IP and complete top-level designs capable of supporting numerous applications, including a discrete secure micro-controller and an integrated secure execution environment (both supporting Root of Trust functionality with secure boot and DICE attestation). OpenTitan will make design and implementation of secure silicon more transparent, trustworthy, and secure for enterprises, platforms, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative, partner-centric project to produce high quality, open IP for instantiation as a full-featured product. This repository exists to enable collaboration across participating OpenTitan project partners and the broader open silicon community.
