Until it is released, the code is under the copyright of ETH Zurich and
the University of Bologna, and may contain confidential and/or unpublished
work. Any reuse/redistribution is strictly forbidden without written
permission from ETH Zurich.
Bug fixes and contributions will eventually be released under the
SolderPad open hardware license in the context of the PULP platform
(http://www.pulp-platform.org), under the copyright of ETH Zurich and the
University of Bologna.
This license is based closely on the Apache License Version 2.0, but is not
approved or endorsed by the Apache Foundation. A copy of the non-modified
Apache License 2.0 can be found at http://www.apache.org/licenses/LICENSE-2.0.
As this license is not currently OSI or FSF approved, the Licensor permits any
Work licensed under this License, at the option of the Licensee, to be treated
as licensed under the Apache License Version 2.0 (which is so approved).
This License is licensed under the terms of this License and in particular
clause 7 below (Disclaimer of Warranties) applies in relation to its use.

“Legal Entity” shall mean the union of the acting entity and all other entities
that control, are controlled by, or are under common control with that entity.
For the purposes of this definition, “control” means (i) the power, direct or
indirect, to cause the direction or management of such entity, whether by
contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the
outstanding shares, or (iii) beneficial ownership of such entity.
“You” (or “Your”) shall mean an individual or Legal Entity exercising
permissions granted by this License.
“Rights” means copyright and any similar right including design right (whether
registered or unregistered), semiconductor topography (mask) rights and
database rights (but excluding Patents and Trademarks).
“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
original version of the Work and any modifications or additions to that Work or
Derivative Works thereof, that is intentionally submitted to Licensor for
inclusion in the Work by the Rights owner or by an individual or Legal Entity
authorized to submit on behalf of the Rights owner. For the purposes of this
definition, “submitted” means any form of electronic, verbal, or written
communication sent to the Licensor or its representatives, including but not
limited to communication on electronic mailing lists, source code control
systems, and issue tracking systems that are managed by, or on behalf of, the
Licensor for the purpose of discussing and improving the Work, but excluding
communication that is conspicuously marked or otherwise designated in writing
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.
