[entropy_src/dv] Recover from RNG failures This commit refactors the RNG and Base VSeq's to recover from simulated failures of the RNG push-pull agent. The interrupt handler thread in then the RNG Vseq has been reorganized to take advantage of the fact that the main thread is now responsible for doing random reconfigurations whenever any failure has been detected. A RNG-failure recovery sequence has then been added to the main thread. The health test interrupt thus just triggers a shutdown of all background operations and a transition to the main thread. Furthermore, the random health-check statistics gathering operations (which were previously only performed after health test failures), have now been added to a general disable_dut task in the base entropy_src vseq, along with the associated random variables.

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.
