Description

The ADI JESD204 Core is released under the following license, which is different than all other HDL cores in this repository.

Please read this, and understand the freedoms and responsibilities you have by using this source code/core.

The JESD204 HDL, is copyright © 2016-2017 Analog Devices Inc.

This core is free software, you can use run, copy, study, change, ask questions about and improve this core. Distribution of source, or resulting binaries (including those inside an FPGA or ASIC) require you to release the source of the entire project (excluding the system libraries provide by the tools/compiler/FPGA vendor). These are the terms of the GNU General Public License version 2 as published by the Free Software Foundation.

This core is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.

You should have received a copy of the GNU General Public License version 2 along with this source code, and binary. If not, see http://www.gnu.org/licenses/.

Commercial licenses (with commercial support) of this JESD204 core are also available under terms different than the General Public License. (e.g. they do not require you to accompany any image (FPGA or ASIC) using the JESD204 core with any corresponding source code.) For these alternate terms you must purchase a license from Analog Devices Technology Licensing Office. Users interested in such a license should contact jesd204-licensing@analog.com for more information. This commercial license is sub-licensable (if you purchase chips from Analog Devices, incorporate them into your PCB level product, and purchase a JESD204 license, end users of your product will also have a license to use this core in a commercial setting without releasing their source code).

In addition, we kindly ask you to acknowledge ADI in any program, application or publication in which you use this JESD204 HDL core. (You are not required to do so; it is up to your common sense to decide whether you want to comply with this request or not.) For general publications, we suggest referencing : “The design and implementation of the JESD204 HDL Core used in this project is copyright © 2016-2017, Analog Devices, Inc.”
