[dv] Gracefully kill simulation When running sims remotely (LSF, etc), if we need to kill a simulation that might be hung, then issuing a TERM signal to the process running the simulation (or `bkill`ing the LSF job) causes the simulation to terminate unexpectedly and uncleanly. If wavedump is enabled, it causes the dump to get corrupted, preventing us from debugging the cause of the hang in the first place. In this patch, there is logic added to the simulation that checks for the presence of a `dv.stop` file in the run directory periodically every 1ms. Whether to enable this logic AND the polling interval can be changed via plusargs. This file can be easily added to the run directory by running `touch <rundir>/dv.stop`. DVsim can use this method rather then killing the process (more updates on that coming soon). Signed-off-by: Srikrishna Iyer <sriyer@google.com>
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.
