[topgen/tlgen] Multi-tiered Xbar The script is to support multi-tiered crossbars on top_earlgrey. Now any crossbar can have connections to other crossbars. It is allowed only one connection between two crossbars at this time. If `xbar: "true"` is defined in the node, the tool does below: - Recognize it as a crossbar connection - Gather downstream addresses and calculate the common address range (*) - If device is a port to another crossbar, the address steering compares list of address range not a single `address_from`, `address_to` Signed-off-by: Eunchan Kim <eunchan@opentitan.org>
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 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 either access it online or build it locally by following the steps below.
$ sudo apt install curl python3 python3-pip $ pip3 install --user -r python-requirements.txt
$ ./util/build_docs.py --preview
This compiles the documentation into ./build/docs and starts a local server, which allows you to access the documentation at http://127.0.0.1:1313.
