Project U-Ray is an attempt at documenting the bitstream format for the Xilinx Ultrascale and Ultrascale+ parts including all parts from the following lines;
- Kintex Ultrascale
- Virtex Ultrascale
- Zynq UltraScale MPSoC
- Kintex UltraScale+
- Virtex UltraScale+
- Zynq UltraScale+ MPSoC
It takes a lot of the learning from Project X-Ray and Project Trellis.

| Board | Maker | Price | Part |
|---|---|---|---|
| Ultra96-V2 Zynq UltraScale+ ZU3EG Development Board (ULTRA96-V2-G) | ??? | Xilinx Zynq UltraScale+ MPSoC ZU3EG | $USD249 |
| Genesys ZU: Zynq Ultrascale+ MPSoC Development Board | Digilent | Xilinx Zynq UltraScale+ MPSoC ZU3EG | $USD1,149 |
We have a goal of initially targeting parts supported by WebPack so that anyone can contribute.
WebPack supports the following parts;
- Kintex UltraScale FPGA - XCKU025, XCKU035
- Kintex UltraScale+ FPGA - XCKU3P, XCKU5P
Zynq UltraScale+ MPSoC -- UltraScale+ MPSoC
- XCZU2EG, XCZU2CG, XCZU3EG, XCZU3CG, XCZU4EG, XCZU4CG, XCZU4EV, XCZU5EG, XCZU5CG, XCZU5EV, XCZU7EV, XCZU7EG, and XCZU7CG
There are a couple of guidelines when contributing to Project U-Ray which are listed here.
All contributions should be sent as GitHub Pull requests.
All software (code, associated documentation, support files, etc) in the
Project U-Ray repository are licensed under the very permissive
Apache-2.0 License. A copy can be found in the LICENSE file.
All new contributions must also be released under this license.
By contributing you agree to the code of conduct. We follow the open source best practice of using the Contributor Covenant for our Code of Conduct.
To improve tracking of who did what, we follow the Linux Kernel's "sign your work" system. This is also called a "DCO" or "Developer's Certificate of Origin".
All commits are required to include this sign off and we use the Probot DCO App to check pull requests for this.
The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as a open-source patch. The rules are pretty simple: if you can certify the below:
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
then you just add a line saying
Signed-off-by: Random J Developer <random@developer.example.org>
using your real name (sorry, no pseudonyms or anonymous contributions.)
You can add the signoff as part of your commit statement. For example:
git commit --signoff -a -m "Fixed some errors."
Hint: If you've forgotten to add a signoff to one or more commits, you can use the following command to add signoffs to all commits between you and the upstream master:
git rebase --signoff upstream/master
In addition to the above contribution guidelines, see the guide to updating the Project U-Ray docs.
