[otbn,dv] Fix `OTBNState.stop()` before initial secure wipe is done Prior to this commit, calling `OTBNState.stop()` before the initial secure wipe has started (the model remains in `FsmState.IDLE` while it waits for the initial URND acknowledge) caused the model to become locked immediately. This is different from the RTL, which in this case correctly completes the secure wipe before becoming locked. This can be reproduced with test `otbn_escalate` and seed `3491964481`. This commit fixes `OTBNState.stop()` to match the correct RTL behavior. Signed-off-by: Andreas Kurth <adk@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.
