[sw, otbn] Acknowledge Done interrupt in ECDSA P-256 test Previously, we weren't clearing the state of the Done interrupt after handling it. As a result, a false interrupt could get signaled immediately after re-enabling it during the execution of the next OTBN program which led Ibex to read out DMEM while OTBN was still busy causing a fatal alert and test failures.

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.
