zGlue Open Hardware License
Version 1.0, June 10, 2019
Copyright 2020 zGlue Inc. <https://zglue.com>
Everyone is permitted to copy and distribute verbatim copies of this license document, 
but changing it is not allowed.

Preamble
The zGlue Open Hardware (zOH) License is a free, CERN-OHL based license related 
to selecting, building, and optimizing custom chips using ChipBuilder by zGlue Inc. 
and available at chipbuilder.zglue.com.  While the CERN-OHL license is an open 
source hardware license, the scope of zOHL also covers software (e.g., open source 
code) needed for the hardware design using ChipBuilder.  
zOH License is adapted from the CERN-OHL license version 2.0.  CERN developed a 
license to promote collaboration among hardware designers and to provide a legal tool 
which supports the freedom to use, study, modify, share and distribute hardware 
designs and products based on those designs.  Use of the zOH License does not imply 
any endorsement by CERN of any Licensor or their designs nor does it imply any 
involvement by CERN in their development.
zOH License allows anyone using ChipBuilder to apply specific design information 
(e.g., netlist, firmware, bill-of-material (BOM), etc.) to design, code, and make custom 
chip(s), and to maximize their chip features by programming integrated peripherals in 
Smart Fabric by zGlue Inc.  Users of the zOH License can select, build, and optimize 
their custom chips by selecting chiplets from zGlues ChipletStore, construct schematics 
and connect to embedded peripherals, and choose from diverse chip package options 
with support for LGA packages.  Users of the zOH License can maximize efficiency with 
zGlue Smart Fabric API (Application Specific Interface) and minimize errors by using 
control Smart Fabric functions through programming, reprogramming their chips on 
the fly, and download and use zGlue software development kit (SDK) and APIs.  
However, the zOH License does not permit anyone without prior authorization from 
zGlue Inc. and separate available license from zGlue Inc., to build, develop, and/or 
modify their own Smart Fabric substrates.  As such, the scope of the zOH License 
excludes the development and/or modifications to the Smart Fabric substrate owned 
by zGlue Inc.  
The precise terms and conditions for copying, distribution, and using of various features 
of ChipBuilder associated with the zOH License follow.

5.1.	You may Convey Covered Source, modified Covered Source or Products to a 
legal entity carrying out development, testing or quality assurance work on 
Your behalf provided that the work is performed on terms which prevent the 
entity from both using the Source or Products for its own internal purposes 
and Conveying the Source or Products or any modifications to them to any 
person other than You.  Any modifications made by the entity shall be 
deemed to be made by You pursuant to subsections 3.2 and 3.3.

6	DISCLAIMER AND LIABILITY

6.1.	DISCLAIMER OF WARRANTY -- The Covered Source and any Products are 
provided "as is" and any express or implied warranties, including, but not 
limited to, implied warranties of merchantability, of satisfactory quality, non-
infringement of third party rights, and fitness for a particular purpose or use 
are disclaimed in respect of any Source or Product to the maximum extent 
permitted by law.  The Licensor makes no representation that any Source or 
Product does not or will not infringe any patent, copyright, trade secret or 
other proprietary right.  The entire risk as to the use, quality, and performance 
of any Source or Product shall be with You and not the Licensor.  This 
disclaimer of warranty is an essential part of this License and a condition for 
the grant of any rights granted under this License.

6.2.	 EXCLUSION AND LIMITATION OF LIABILITY -- The Licensor shall, to the 
maximum extent permitted by law, have no liability for direct, indirect, special, 
incidental, consequential, exemplary, punitive or other damages of any 
character including, without limitation, procurement of substitute goods or 
services, loss of use, data or profits, or business interruption, however caused 
and on any theory of contract, warranty, tort (including negligence), product 
liability or otherwise, arising in any way in relation to the Covered Source, 
modified Covered Source and/or the Making or Conveyance of a Product, 
even if advised of the possibility of such damages, and You shall hold the 
Licensor(s) free and harmless from any liability, costs, damages, fees and 
expenses, including claims by third parties, in relation to such use.

7	Patents

7.1.	Subject to the terms and conditions of this License, each Licensor hereby 
grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, 
irrevocable (except as stated in this section 6, or where terminated by the 
Licensor for cause) patent license to Make, have Made, use, offer to sell, sell, 
import, and otherwise transfer the Covered Source and Products, where such 
license applies only to those patent claims licensable by such Licensor that 
are necessarily infringed by exercising rights under the Covered Source as 
Conveyed by that Licensor.

7.2.	If You institute patent litigation against any entity (including a cross-claim or 
counterclaim in a lawsuit) alleging that the Covered Source or a Product 
constitutes direct or contributory patent infringement, or You seek any 
declaration that a patent licensed to You under this License is invalid or 
unenforceable then any rights granted to You under this License shall 
terminate as of the date such process is initiated.

8	General

8.1.	If any provisions of this License are or subsequently become invalid or 
unenforceable for any reason, the remaining provisions shall remain effective.

8.2.	You shall not use any of the name (including acronyms and abbreviations), 
image, or logo by which the Licensor is known, except where needed to 
comply with section 3, or where the use is otherwise allowed by law.  Any 
such permitted use shall be factual and shall not be made so as to suggest 
any kind of endorsement or implication of involvement by the Licensor or its 
personnel.

8.3.	zGlue Inc. may publish updated versions and variants of this License which it 
considers to be in the spirit of this version, but may differ in detail to address 
new problems or concerns.  New versions will be published with a unique 
version number and a variant identifier specifying the variant.  If the Licensor 
has specified that a given variant applies to the Covered Source without 
specifying a version, You may treat that Covered Source as being released 
under any version of the zOH License with that variant.  If no variant is 
specified, the Covered Source shall be treated as being released under zOH 
License V. 1.0.  The Licensor may also specify that the Covered Source is 
subject to a specific version of the zOH License or any later version in which 
case You may apply this or any later version of zOH License with the same 
variant identifier published by zGlue Inc.

8.4.	This License shall terminate with immediate effect if You fail to comply with 
any of its terms and conditions.

8.5.	However, if You cease all breaches of this License, then Your License from 
any Licensor is reinstated unless such Licensor has terminated this License 
by giving You, while You remain in breach, a notice specifying the breach and 
requiring You to cure it within 30 days, and You have failed to come into 
compliance in all material respects by the end of the 30 day period. Should 
You repeat the breach after receipt of a cure notice and subsequent 
reinstatement, this License will terminate immediately and permanently. 
Section 6 shall continue to apply after any termination.

8.6.	This License shall not be enforceable except by a Licensor acting as such, 
and third party beneficiary rights are specifically excluded.

9	No Surrender of Others' Freedom.

9.1.	If conditions are imposed on you (whether by court order, agreement or 
otherwise) that contradict the conditions of this License, they do not excuse 
you from the conditions of this License. If you cannot convey a covered work 
so as to satisfy simultaneously your obligations under this License and any 
other pertinent obligations, then as a consequence you may not convey it at 
all.
