[prim] Allow disabling SVAs ensuring REQ is held until ACK at run time Previously, a parameter was used to disable these checks statically. While we need to be able to disable these checks during abnormal operating conditions (e.g. LC escalation), violating such assertions in normal operation can be very critical and can lock up the system (e.g. CDC). We must be able to catch such issues. Thus, this commit replaces the parameter by a new input signal to gate the corresponding assertion at run time. This resolves lowRISC/OpenTitan#7308.

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.
