[entropy_src/dv] Support complete backpressure Testing the cs_aes_halt_req/ack port calls for improving backpressure support in the entire entropy_src pipeline, as submitted in PR #14644. These changes in turn actually simplify some of the timing subtleties that have to be done in the DV scoreboard. Some of the DV timing hacks done prior to this commit no longer accurately predict the timing of the entropy source. Most notably, data samples no longer linger in the RNG bit-select FIFO until another RNG sample is recieved. This commit also updates the assertion tweaks that need to be done to support the backpressure changes. This is because there is another instance of prim_mubi4_sync that needs to be relaxed when bad Mubi values are injected into the pipeline.

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.
