In this HDL repository, there are many different and unique modules, consisting
|
||||||
|
of various HDL (Verilog or VHDL) components. The individual modules are
|
||||||
|
developed independently, and may be accompanied by separate and unique license
|
||||||
|
terms (such as GPL, LGPL, BSD, modified BSD, commercial or others). Your license
|
||||||
|
rights with respect to individual modules accompanied by separate license terms
|
||||||
|
are defined by those terms. The license agreement for each module is generally
|
||||||
|
located in the module source code. Nothing else shall restrict, limit, or
|
||||||
|
otherwise affect any rights or obligations you may have, or conditions to which
|
||||||
|
you may be subject, under such license terms. This agreement does not limit your
|
||||||
|
rights under, or grant you rights that supersede, the license terms of any
|
||||||
|
particular module.
|
||||||
|
|
||||||
All rights reserved.
|
The mere aggregation of these modules (putting them side by side in the same
|
||||||
|
source code repository or on a hard disk) does not mean that there is one master
|
||||||
|
license for all the files. It is up to you, the user, to ensure that during the
|
||||||
|
building a project, which combines these modules together so that they form a
|
||||||
|
bit file (either one, or multiple for partial reconfiguration), all the individual
|
||||||
|
licenses are compatible. For example, if a single module is covered by the GPL,
|
||||||
|
the whole combination must also be released under the GPL—if you can't, or
|
||||||
|
won't, do that, you may not distribute the resulting bit file.
|
||||||
|
|
||||||
Redistribution and use in source and binary forms, with or without modification,
|
The majority of ADI created modules are dual-licensed, allowing the user to pick
|
||||||
are permitted provided that the following conditions are met:
|
which license they want to use, (and the any rights and obligations they have).
|
||||||
- Redistributions of source code must retain the above copyright
|
- The ADI BSD license. (which allows you to makeg bit files, and not release your
|
||||||
notice, this list of conditions and the following disclaimer.
|
source, as long as it attaches to an ADI device) o This is not truly open
|
||||||
- Redistributions in binary form must reproduce the above copyright
|
source, since it does place extra restrictions on developers.
|
||||||
notice, this list of conditions and the following disclaimer in
|
- The GPL v2 license (which allows you to make bit files, but you must release
|
||||||
the documentation and/or other materials provided with the
|
all other HDL (except vendor produced, which we consider a run-time library,
|
||||||
distribution.
|
permitted by GPL section 3), along with your bitfile). o This is truly open
|
||||||
- Neither the name of Analog Devices, Inc. nor the names of its
|
source, and places no additional restrictions on use or fields of endeavor. The
|
||||||
contributors may be used to endorse or promote products derived
|
GPL is ideal for use cases such as open source projects with open source
|
||||||
from this software without specific prior written permission.
|
distribution, student/academic purposes, hobby projects, internal research
|
||||||
- The use of this software may or may not infringe the patent rights
|
projects without external distribution, or other projects where all GPL
|
||||||
of one or more patent holders. This license does not release you
|
obligations can be met.
|
||||||
from the requirement that you obtain separate licenses from these
|
|
||||||
patent holders to use this software.
|
In these cases, support is handled via web (https://ez.analog.com/community/fpga),
|
||||||
- Use of the software either in source or binary form, must be run
|
on a best effort basis. If you do not feel we are answering your questions
|
||||||
on or directly connected to an Analog Devices Inc. component.
|
fast enough on engineerzone - remember that our best efforts may not match your
|
||||||
|
product development schedule. Free, non-deterministic support is not a replacement
|
||||||
|
for professional services (contractors). If you need something done in a specific
|
||||||
|
time frame - hire a professional. Just as you are free to use HDL modules you
|
||||||
|
find here (under that module's license), you are free use an alternative,
|
||||||
|
which may include commercial/deterministic support.
|
||||||
|
|
||||||
|
Specific modules which do not follow this (this list may not be complete, it's
|
||||||
|
up to each user to check each module license):
|
||||||
|
- SPDIF : which is released under the LGPL license only.
|
||||||
|
+ Please go to https://opencores.org/project, spdif_interface for support
|
||||||
|
- The ADI created JESD Core, which is released under the GPL and a
|
||||||
|
commercial license only.
|
||||||
|
+ The commercial license gives you the full rights to create and distribute
|
||||||
|
bit files on your own terms without any open source license obligations,
|
||||||
|
and special avenues for support may be possible.
