OpenIPCore Hardware General Public License "OHGPL"
Draft Version 0.20-15092000 September 2000
Copyright (C) 2000 OpenIPCore Organization.
Everyone is permitted to copy and distribute and modify this document
under the terms of the GNU Free Documentation License.
Preamble
========
The preamble is part of the license and the license and its preamble
can not be split out.
Definitions:
SYSTEM
Is any thing that works or supposed to work to do some
operations depending on some specific inputs and produce
some results.
HARDWARE DESIGN:
(The terms HARDWARE DESIGN and DESIGN can be used
interchangeably in the license)
Is any work that defines, describes or simulates a system or
part of a system that could be physically implemented. This
includes but not limited to, system architectures, design
ideas, design description, micro-codes or hardware
instructions.
HARDWARE DESIGN DESCRIPTION:
(The terms HARDWARE DESIGN DESCRIPTION and DESIGN
DESCRIPTION can be used interchangeably in the license)
Is any form of documentation or supporting materials that
defines and identifies the Hardware design, how it can be
implemented and/or tested. This includes but not limited to,
HDL codes, schematics, net-lists, PCB layouts, chip and
silicon cell layout, timing diagrams, truth tables, flow
charts, state diagrams, block diagrams or written (digitally
or physically) documentation.
Hardware design files/ CAD files:
Are set of files that are used to describe
the hardware design, its implementation or testing or some
parts of it.
Fabrication files:
Are set of files that are used to physically implement
the design or part of it.
COPYING A HARDWARE DESIGN DESCRIPTION:
Is the act of duplicating the design
description or CAD files in anyway.
DISTRIBUTION OF A HARDWARE DESIGN:
Is the act of publishing and making the design description
available for more activities or people.
MODIFICATION OF A DESIGN:
Is the act of reproducing the design in order to alter
(not necessarily to succeed to improve) the design itself
or the description of the design.
IMPLEMENTATION OF A DESIGN:
Is the act of producing/reproducing the hardware design or
part of it to get the physical or part of the physical system.
The Derivative work
means any changes, improvements or porting the original work
to other environments or platforms (e.g. different hardware
target, different PLD....). This may vary depending on the
type of the hardware design itself.
The based work
is the act of using the design AS IS without any modification
as a building block or module of other design. (e.g. like using
the design as a daughter board for a large system, or using the
HDL code in SoC core).
OpenIPCore/OpenCores License terms.
===================================
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
1. This license applies to hardware designs, hardware design
description, CAD or Fabrication files or any other work which
contains a notice placed by the copyright holder saying it may
be distributed under the terms of this License.
2. You may copy, distribute and/or implement this Hardware Design
or any portion of it as is. Any time you copy or distribute this
design you have to provide all of the source files and
documentations that came with the original work or put them in
a public place that anyone can reach without any kind of
restrictions.
3. You can not sell the design description, design files or
fabrication files but you may charge fee for the physical act
of transferring a copy
4. You can implement the design and charge fees for the physical
hardware and you have to provide notice for the public about
the source of the design description.
5. Any modification of this hardware design or any derivative work
from it should be documented by providing list of changes, reasons
behind the changes and the date of change.
6. You are allowed to use the design or design files on any work
based on the hardware design.
7. You may not copy, modify, sublicense, or distribute the design/design
description or files except as expressly provided under this License.
Any attempt otherwise to copy, modify, sublicense or distribute the
design/design description or files is void, and will automatically
terminate your rights under this License. However, parties who have
received copies, or rights, from you under this License will not
have their licenses terminated so long as such parties remain in
full compliance.
8. Each time you redistribute the design description or files,
the recipient automatically receives a license from the original
licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted
herein.
9. You are not required to accept this License, since you have
not signed it. However, nothing else grants you permission
to modify or distribute the hardware design or its derivative
works. These actions are prohibited by law if you do not
accept this License. Therefore, by modifying, distributing
or implementing the hardware design (or any work based on the
hardware design), you indicate your acceptance of this License
to do so, and all its terms and conditions for copying,
distributing or modifying the hardware design or works based
on it.
10. NO WARRANTY of any kind is provided on the functionality,
performance or risks cased by using this Hardware Design.
NO WARRANTY
===========
11.a. BECAUSE THE HARDWARE DESIGN IS LICENSED FREE OF CHARGE,
THERE IS NO WARRANTY FOR IT, TO THE EXTENT PERMITTED BY APPLICABLE
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES PROVIDE THE HARDWARE DESIGN IMPLEMENTATION
"AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE
RISK AS TO THE QUALITY AND PERFORMANCE OF THE HARDWARE DESIGN IS
WITH YOU. SHOULD THE DESIGN PROVE DEFECTIVE, YOU ASSUME THE COST
OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
11.b. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO
IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
MODIFY AND/OR REDISTRIBUTE THE HARDWARE DESIGN AS PERMITTED ABOVE,
BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
INABILITY TO USE THE HARDWARE DESIGN (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES
SUSTAINED BY YOU OR THIRD PARTIES OR ANY OTHER KIND OF LOSSES
OR A FAILURE OF THE HARDWARE DESIGN IMPLEMENTATION TO OPERATE
WITH ANY OTHER SYSTEMS), EVEN IF SUCH HOLDER OR OTHER PARTY
HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
11.c IN CASE OF THE PHYSICAL IMPLEMINTATION, THE IMPLIMENTER CAN
PROVIDE WARRANTIES ON THE PHYSICAL HARDWARE AND CHARGE FOR FEES
FOR SUCH WARRANTIES.
