+
+      "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

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      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:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) 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
+
+      (d) 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.

+# BAG (BAG AMS Generator) Primitives Library for [SKY130](https://github.com/google/skywater-pdk)
+
+This repository contains the required primitives to use BAG3 framework with
+[the Google skywater-pdk, a fully open source, manufacturable PDK for
+SkyWater's 130nm (SKY13) process node](https://github.com/google/skywater-pdk).
+
+When combined with appropriate generator code, the primitives enables the
+creation of analog integrated circuits that are manufacturable at
+[SkyWater Technologies](https://www.skywatertechnology.com/) commercially or
+through programs like
+[Google's no-cost MPW shuttle program for open source designs, done in collaboration with efabless](https://efabless.com/open_shuttle_program).
+
+## What is BAG?
+
+[BAG AMS Generator (BAG)](https://github.com/ucb-art/bag) is the 3rd generation
+of the Berkeley Analog Generator framework (see also
+[BAG v2 framework](https://github.com/ucb-art/bag)).
+
+
+## License
+
+To enable wide compatibility with the existing BAG ecosystem, this repository
+is dual-licensed. It is available to you under your choice of the
+[the Apache 2.0 license](LICENSE) or a [3 clause BSD style](LICENSE.alternative).

+Google Open Source Community Guidelines
+---------------------------------------
+
+.. community_guidelines_text
+
+At Google, we recognize and celebrate the creativity and collaboration
+of open source contributors and the diversity of skills, experiences,
+cultures, and opinions they bring to the projects and communities they
+participate in.
+
+Every one of Google's open source projects and communities are inclusive
+environments, based on treating all individuals respectfully, regardless
+of gender identity and expression, sexual orientation, disabilities,
+neurodiversity, physical appearance, body size, ethnicity, nationality,
+race, age, religion, or similar personal characteristic.
+
+We value diverse opinions, but we value respectful behavior more.
+
+Respectful behavior includes:
+
+-  Being considerate, kind, constructive, and helpful.
+-  Not engaging in demeaning, discriminatory, harassing, hateful,
+   sexualized, or physically threatening behavior, speech, and imagery.
+-  Not engaging in unwanted physical contact.
+
+Some Google open source projects
+`may adopt <https://opensource.google/docs/releasing/preparing/#conduct>`__
+an explicit project code of conduct, which may have additional detailed
+expectations for participants. Most of those projects will use our
+`modified Contributor Covenant <https://opensource.google/docs/releasing/template/CODE_OF_CONDUCT/>`__.
+
+Resolve peacefully
+~~~~~~~~~~~~~~~~~~
+
+We do not believe that all conflict is necessarily bad; healthy debate
+and disagreement often yields positive results. However, it is never
+okay to be disrespectful.
+
+If you see someone behaving disrespectfully, you are encouraged to
+address the behavior directly with those involved. Many issues can be
+resolved quickly and easily, and this gives people more control over the
+outcome of their dispute. If you are unable to resolve the matter for
+any reason, or if the behavior is threatening or harassing, report it.
+We are dedicated to providing an environment where participants feel
+welcome and safe.
+
+Reporting problems
+~~~~~~~~~~~~~~~~~~
+
+Some Google open source projects may adopt a project-specific code of
+conduct. In those cases, a Google employee will be identified as the
+Project Steward, who will receive and handle reports of code of conduct
+violations. In the event that a project hasn’t identified a Project
+Steward, you can report problems by emailing opensource@google.com.
+
+We will investigate every complaint, but you may not receive a direct
+response. We will use our discretion in determining when and how to
+follow up on reported incidents, which may range from not taking action
+to permanent expulsion from the project and project-sponsored spaces. We
+will notify the accused of the report and provide them an opportunity to
+discuss it before any action is taken. The identity of the reporter will
+be omitted from the details of the report supplied to the accused. In
+potentially harmful situations, such as ongoing harassment or threats to
+anyone's safety, we may take action without notice.

+How to Contribute
+=================
+
+We'd love to accept your patches and contributions to this project.
+There are just a few small guidelines you need to follow.
+
+Contributor License Agreement
+-----------------------------
+
+Contributions to this project must be accompanied by a Contributor
+License Agreement. You (or your employer) retain the copyright to your
+contribution; this simply gives us permission to use and redistribute
+your contributions as part of the project. Head over to
+https://cla.developers.google.com/ to see your current agreements on
+file or to sign a new one.
+
+You generally only need to submit a CLA once, so if you've already
+submitted one (even if it was for a different project), you probably
+don't need to do it again.
+
+Code reviews
+------------
+
+All submissions, including submissions by project members, require
+review. We use GitHub pull requests for this purpose. Consult `GitHub
+Help <https://help.github.com/articles/about-pull-requests/>`__ for more
+information on using pull requests.
