[entropy_src/rtl] Fine-tune SHA3 intake pipline Since the SHA3 conditioner is not cleared on disable, it is important to in verification carefully predict which words actually get inserted into it as disable events occur. This type of verificaiton problem has already been solved for the health test statistics. Therefore this commit lets all samples that have already been health checked into the SHA engine, so that verification can use the complete health-checked dataset when predicting conditioning outputs. This will also preserve a handful of observe-fifo words that were previously being marked as "Dropped" by verification. Also some bypass words will also be preserved in the pipeline for one additional cycle as they linger in the precon FIFO, but they will be cleared immediately afterwards, and thus should not impact verification.

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.
