[util, reggen] Support standardized cdc handling for regfile - Support two asynchronous schemes on regfile - Fully asynchronous - a tlul_fifo_async directly instantiated in regfile - Mixed asynchronous - allow user to selectively mark registers as async - These two schemes are mutually exclusive - Add an 'async' key for bus interfaces to indicate the reg block is fully asynchornous - Add an 'async' key per register to indicate register clock domain - Add extra clock/reset ports to reg module - Add prim_subreg_cdc to handle regiser domain clock crossing Signed-off-by: Timothy Chen <timothytim@google.com> [aon_timer] Updates to aon_timer to experiment with new cdc scheme 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.
