[top_earlgrey] Avoid non-existent pins in XDC file for CW310 A Vivado synthesis of the CW310 design results in the following warnings, coming from two pins which are declared in the XDC file, but don't exist as top-level ports in the design. Remove them from the XDC file by commenting them out. (This way the XDC file has still all possible device pins in there, but only the used ones are actually enabled, a common technique for those files.) ``` CRITICAL WARNING: [Common 17-55] 'set_property' expects at least one object.

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.
