[otbn] Support for an unbounded x1 call stack in otbn-rig The random instruction generator now avoids reading (and popping) from the call stack so many times that there's no architectural value. Doing so will trigger an alert (not currently handled in either the ISS or the RTL), so we don't want to do it by accident. Signed-off-by: Rupert Swarbrick <rswarbrick@lowrisc.org>
OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
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. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
