  1. License Grants and Conditions

2.1. Grants

Each Contributor hereby grants You a world-wide, royalty-free, non-exclusive license:

(a) under intellectual property rights (other than patent or trademark) Licensable by such Contributor to use, reproduce, make available, modify, display, perform, distribute, and otherwise exploit its Contributions, either on an unmodified basis, with Modifications, or as part of a Larger Work; and

(b) under Patent Claims of such Contributor to make, use, sell, offer for sale, have made, import, and otherwise transfer either its Contributions or its Contributor Version.

2.2. Effective Date

The licenses granted in Section 2.1 with respect to any Contribution become effective for each Contribution on the date the Contributor first distributes such Contribution.

2.3. Limitations on Grant Scope

The licenses granted in this Section 2 are the only rights granted under this License. No additional rights or licenses will be implied from the distribution or licensing of Covered Hardware Description under this License. Notwithstanding Section 2.1(b) above, no patent license is granted by a Contributor:

(a) for any code that a Contributor has removed from Covered Hardware Description; or

(b) for infringements caused by: (i) Your and any other third party's modifications of a Covered Hardware Description, or (ii) the combination of its Contributions with other Source (except as part of its Contributor Version); or

(c) under Patent Claims infringed by a Covered Hardware Description in the absence of its Contributions.

This License does not grant any rights in the trademarks, service marks, or logos of any Contributor (except as may be necessary to comply with the notice requirements in Section 3.4).

2.4. Subsequent Licenses

No Contributor makes additional grants as a result of Your choice to distribute the Covered Hardware Description under a subsequent version of this License (see Section 10.2) or under the terms of a Secondary License (if permitted under the terms of Section 3.3).

2.5. Representation

Each Contributor represents that the Contributor believes its Contributions are its original creation(s) or it has sufficient rights to grant the rights to its Contributions conveyed by this License.

2.6. Fair Use

This License is not intended to limit any rights You have under applicable copyright doctrines of fair use, fair dealing, or other equivalents.

2.7. Conditions

Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in Section 2.1.

  1. Responsibilities

3.1. Distribution of Source Form

All distribution of Covered Hardware Description in Source Code Form, including any Modifications that You create or to which You contribute, must be under the terms of this License. You must inform recipients that the Source Code Form of the Covered Hardware Description is governed by the terms of this License, and how they can obtain a copy of this License. You may not attempt to alter or restrict the recipients' rights in the Source Code Form.

3.2. Distribution of Processed Form

If You distribute Covered Hardware Description in Processed Form then:

(a) such Covered Hardware Description must also be made available in Source Code Form, as described in Section 3.1, and You must inform recipients of the Processed Form how they can obtain a copy of such Source Code Form by reasonable means in a timely manner, at a charge no more than the cost of distribution to the recipient; and

(b) You may distribute such Processed Form under the terms of this License, or sublicense it under different terms, provided that the license for the Processed Form does not attempt to limit or alter the recipients' rights in the Source Code Form under this License.

3.3. Distribution of a Larger Work

You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the requirements of this License for the Covered Hardware Description. If the Larger Work is a combination of a Covered Hardware Description with a work governed by a Secondary License, and the Covered Hardware Description is not Incompatible With Secondary Licenses, this License permits You to additionally distribute such Covered Hardware Description under the terms of that Secondary License, so that the recipient of the Larger Work may, at their option, further distribute the Covered Hardware Description under the terms of either this License or that Secondary License.

3.4. Notices

You may not remove or alter the substance of any license notices (including copyright notices, patent notices, disclaimers of warranty, or limitations of liability) contained within the Source Code Form of the Covered Hardware Description, except that You may alter any license notices to the extent required to remedy known factual inaccuracies.

3.5. Application of Additional Terms

You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of a Covered Hardware Description. However, You may do so only on Your own behalf, and not on behalf of any Contributor. You must make it absolutely clear that any such warranty, support, indemnity, or liability obligation is offered by You alone, and You hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a result of warranty, support, indemnity or liability terms You offer. You may include additional disclaimers of warranty and limitations of liability specific to any jurisdiction.

  1. Inability to Comply Due to Statute or Regulation

If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Hardware Description due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be placed in a text file included with all distributions of the Covered Hardware Description under this License. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it.

  1. Termination

5.1. The rights granted under this License will terminate automatically if You fail to comply with any of its terms. However, if You become compliant, then the rights granted under this License from a particular Contributor are reinstated (a) provisionally, unless and until such Contributor explicitly and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor fails to notify You of the non-compliance by some reasonable means prior to 60 days after You have come back into compliance. Moreover, Your grants from a particular Contributor are reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by some reasonable means, this is the first time You have received notice of non-compliance with this License from such Contributor, and You become compliant prior to 30 days after Your receipt of the notice.

5.2. If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory judgment actions, counter-claims, and cross-claims) alleging that a Contributor Version directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Hardware Description under Section 2.1 of this License shall terminate.

5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or Your distributors under this License prior to termination shall survive termination.

    1. Disclaimer of Warranty *
  • ------------------------- *
  •                                                                  *
  • The Covered Hardware Description is provided under this License on *
  • an "as is" basis, without warranty of any kind, either expressed, *
  • implied, or statutory, including, without limitation, warranties *
  • that the Covered Hardware Description is free of defects, *
  • merchantable, fit for a particular purpose or non-infringing. The *
  • entire risk as to the quality and performance of the Covered *
  • Hardware Description is with You. Should any Covered Hardware *
  • Description prove defective in any respect, You (not any *
  • Contributor) assume the cost of any necessary servicing, repair, or *
  • correction. This disclaimer of warranty constitutes an essential *
  • part of this License. No use of any Covered Hardware Description is *
  • authorized under this License except under this disclaimer. *
  •                                                                  *

  •                                                                  *
    1. Limitation of Liability *
  • -------------------------- *

  • Under no circumstances and under no legal theory, whether tort *
  • (including negligence), contract, or otherwise, shall any *
  • Contributor, or anyone who distributes Covered Hardware Description *
  • as permitted above, be liable to You for any direct, indirect, *
  • special, incidental, or consequential damages of any character *
  • including, without limitation, damages for lost profits, loss of *
  • goodwill, work stoppage, computer failure or malfunction, or any *
  • and all other commercial damages or losses, even if such party *
  • shall have been informed of the possibility of such damages. This *
  • limitation of liability shall not apply to liability for death or *
  • personal injury resulting from such party's negligence to the *
  • extent applicable law prohibits such limitation. Some *
  • jurisdictions do not allow the exclusion or limitation of *
  • incidental or consequential damages, so this exclusion and *
  • limitation may not apply to You. *
  •                                                                  *
  1. Litigation

Any litigation relating to this License may be brought only in the courts of a jurisdiction where the defendant maintains its principal place of business and such litigation shall be governed by laws of that jurisdiction, without reference to its conflict-of-law provisions. Nothing in this Section shall prevent a party's ability to bring cross-claims or counter-claims.

  1. Miscellaneous

This License represents the complete agreement concerning the subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. Any law or regulation which provides that the language of a contract shall be construed against the drafter shall not be used to construe this License against a Contributor.

  1. Versions of the License

10.1. New Versions

Julius Baxter is the license steward. Except as provided in Section 10.3, no one other than the license steward has the right to modify or publish new versions of this License. Each version will be given a distinguishing version number.

10.2. Effect of New Versions

You may distribute the Covered Hardware Description under the terms of the version of the License under which You originally received the Covered Hardware Description, or under the terms of any subsequent version published by the license steward.

10.3. Modified Versions

If you create designs not governed by this License, and you want to create a new license for such designs, you may create and use a modified version of this License if you rename the license and remove any references to the name of the license steward (except to note that such modified license differs from this License).
