[otbn,dv] Add the "BadAtEnd" generator to RIG This generates a branch, jump or loop as the last instruction in a loop. To do this, we also factor out the gen_head method in the Branch generator. This is the bit that generates the actual branch instruction, which is what we need for BadAtEnd. Similarly, we factor out a _pick_head method in the Loop generator. This is in charge of picking the LOOP/LOOPI instruction (it also returns some auxiliary information about loop shape that we need). 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.
