+“Source” form shall mean the preferred form for making modifications, including
+but not limited to source code, net lists, board layouts, CAD files,
+documentation source, and configuration files.
+
+“Object” form shall mean any form resulting from mechanical transformation or
+translation of a Source form, including but not limited to compiled object
+code, generated documentation, the instantiation of a hardware design and
+conversions to other media types, including intermediate forms such as
+bytecodes, FPGA bitstreams, artwork and semiconductor topographies (mask
+works).
+
+“Work” shall mean the work of authorship, whether in Source form or other
+Object form, made available under the License, as indicated by a Rights notice
+that is included in or attached to the work (an example is provided in the
+Appendix below).
+
+“Derivative Works” shall mean any work, whether in Source or Object form, that
+is based on (or derived from) the Work and for which the editorial revisions,
+annotations, elaborations, or other modifications represent, as a whole, an
+original work of authorship. For the purposes of this License, Derivative Works
+shall not include works that remain separable from, or merely link (or bind by
+name) or physically connect to or interoperate with the interfaces of, the Work
+and Derivative Works thereof.
+
+“Contribution” shall mean any design or work of authorship, including the

+by the Rights owner as “Not a Contribution.”
+
+“Contributor” shall mean Licensor and any individual or Legal Entity on behalf
+of whom a Contribution has been received by Licensor and subsequently
+incorporated within the Work.
+
+2. Grant of License. Subject to the terms and conditions of this License, each
+Contributor hereby grants to You a perpetual, worldwide, non-exclusive,
+no-charge, royalty-free, irrevocable license under the Rights to reproduce,
+prepare Derivative Works of, publicly display, publicly perform, sublicense,
+and distribute the Work and such Derivative Works in Source or Object form and
+do anything in relation to the Work as if the Rights did not exist.
+
+3. Grant of Patent License. Subject to the terms and conditions of this
+License, each Contributor hereby grants to You a perpetual, worldwide,
+non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this
+section) patent license to make, have made, use, offer to sell, sell, import,
+and otherwise transfer the Work, where such license applies only to those
+patent claims licensable by such Contributor that are necessarily infringed by
+their Contribution(s) alone or by combination of their Contribution(s) with the
+Work to which such Contribution(s) was submitted. If You institute patent
+litigation against any entity (including a cross-claim or counterclaim in a
+lawsuit) alleging that the Work or a Contribution incorporated within the Work
+constitutes direct or contributory patent infringement, then any patent
+licenses granted to You under this License for that Work shall terminate as of
+the date such litigation is filed.
+
+4. Redistribution. You may reproduce and distribute copies of the Work or
+Derivative Works thereof in any medium, with or without modifications, and in
+Source or Object form, provided that You meet the following conditions:
+
+    You must give any other recipients of the Work or Derivative Works a copy
+    of this License; and
+
+    You must cause any modified files to carry prominent notices stating that
+    You changed the files; and
+
+    You must retain, in the Source form of any Derivative Works that You
+    distribute, all copyright, patent, trademark, and attribution notices from
+    the Source form of the Work, excluding those notices that do not pertain to
+    any part of the Derivative Works; and
+
+    If the Work includes a “NOTICE” text file as part of its distribution, then
+    any Derivative Works that You distribute must include a readable copy of
+    the attribution notices contained within such NOTICE file, excluding those
+    notices that do not pertain to any part of the Derivative Works, in at
+    least one of the following places: within a NOTICE text file distributed as
+    part of the Derivative Works; within the Source form or documentation, if
+    provided along with the Derivative Works; or, within a display generated by
+    the Derivative Works, if and wherever such third-party notices normally
+    appear. The contents of the NOTICE file are for informational purposes only
+    and do not modify the License. You may add Your own attribution notices
+    within Derivative Works that You distribute, alongside or as an addendum to
+    the NOTICE text from the Work, provided that such additional attribution
+    notices cannot be construed as modifying the License. You may add Your own
+    copyright statement to Your modifications and may provide additional or
+    different license terms and conditions for use, reproduction, or
+    distribution of Your modifications, or for any such Derivative Works as a
+    whole, provided Your use, reproduction, and distribution of the Work
+    otherwise complies with the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise, any
+Contribution intentionally submitted for inclusion in the Work by You to the
+Licensor shall be under the terms and conditions of this License, without any
+additional terms or conditions. Notwithstanding the above, nothing herein shall
+supersede or modify the terms of any separate license agreement you may have
+executed with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade names,
+trademarks, service marks, or product names of the Licensor, except as required
+for reasonable and customary use in describing the origin of the Work and
+reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or agreed to in
+writing, Licensor provides the Work (and each Contributor provides its
+Contributions) on an “AS IS” BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY
+KIND, either express or implied, including, without limitation, any warranties
+or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+PARTICULAR PURPOSE. You are solely responsible for determining the
+appropriateness of using or redistributing the Work and assume any risks
+associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory, whether in
+tort (including negligence), contract, or otherwise, unless required by
+applicable law (such as deliberate and grossly negligent acts) or agreed to in
+writing, shall any Contributor be liable to You for damages, including any
+direct, indirect, special, incidental, or consequential damages of any
+character arising as a result of this License or out of the use or inability to
+use the Work (including but not limited to damages for loss of goodwill, work
+stoppage, computer failure or malfunction, or any and all other commercial
+damages or losses), even if such Contributor has been advised of the
+possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing the Work or
+Derivative Works thereof, You may choose to offer, and charge a fee for,
+acceptance of support, warranty, indemnity, or other liability obligations
+and/or rights consistent with this License. However, in accepting such
+obligations, You may act only on Your own behalf and on Your sole
+responsibility, not on behalf of any other Contributor, and only if You agree
+to indemnify, defend, and hold each Contributor harmless for any liability
+incurred by, or claims asserted against, such Contributor by reason of your
+accepting any such warranty or additional liability.
