[otbn,rtl] Use err_bits, not err_bits_q for alerts[AlertFatal] This fixes a bug introduced by 75885e6 where we'd only generate fatal alerts when an operation finished. One problem with this is that secure wipe takes ~100 cycles, so delays the alert. Another (more serious) problem is that it means alerts are squashed altogether when OTBN isn't running. Note that the timing of alerts[AlertFatal] now matches that of the FATAL_ALERT_CAUSE register, which should make a bit more sense. 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.
