[otbn,dv] Add dummy instructions to pairwise covergroup This covergroup is supposed to be tracking pairs of instructions. I'd carefully avoided putting ECALL in the "last_cp" coverpoint (since if you get an ECALL, you'll not have a following instruction). Unfortunately, I hadn't looked properly at the list of mnemonics and had forgotten "dummy-insn" and "??" which are used for invalid instructions and failed integrity checks, respectively. Add them to avoid illegal bin reports. 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.
