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,

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.
