[tlul] - Update to prevent x on d_error The scenario is as follows: - A transaction is accepted (reqfifo is updated) - reqfifo attributes are used in the next cycle to set payload such as d_error - However, if downstream takes more than 1 cycle to return, the response during that cycle is unknown, and the assertion fails. This stall is quite likely to happen in a real system, so d_error is now also qualified with d_valid like the return data. Signed-off-by: Timothy Chen <timothytim@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.
