[otbn,dv] Dump an "expected end address" symbol from the RIG The random instruction generator currently tries hard not to generate any invalid instructions or trigger any errors on the processor. We're going to start generating errors soon, but we don't want to do so "accidentally". To help us avoid that, we add an "_expected_end_addr" symbol to the generated ELF file. A followup commit will teach the simulator to spot that address and generate an "oh no! the world is broken!" error if simulation stops on the wrong address. Note that this change won't give us any extra confidence in the RTL, but it should make it easier to debug if we make a mistake in the RIG and it's not generating quite the program paths we thought it was.

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.
