The GF180MCU open source PDK is a collaboration between Google and GlobalFoundries to provide a fully open source process design kit (PDK) and related resources to enable the creation of designs manufacturable at GlobalFoundries's facility on their 0.18um 3.3V/6V MCU process technology.

The GF180MCU documentation can be found at <https://gf180mcu-pdk.rtfd.io>.

Current Status -- |current-status|
==================================

.. current_status_text

*Warning*
   Google and GlobalFoundries are currently treating the current content as an **experimental preview** / **alpha release**.

While the GF180MCU process node and the PDK from which this open source release was derived have been used to create many designs that have been successfully manufactured commercially in significant quantities, the open source PDK is not intended to be used for production settings at this current time. It *should* be usable for doing test chips and initial design verification (but this is not guaranteed).

Google, GlobalFoundries and our partners are currently doing internal validation and test designs, including silicon validation or the released data and plan to publish these results.

The PDK will be tagged with a production version when ready to do production design, see the "`Versioning Information <docs/versioning.rst>`_" section for a full description of the version numbering scheme.

To get notified about future new releases of the PDK, and other important news, please sign up on the
`gf180mcu-pdk-announce mailing list <https://groups.google.com/forum/#!forum/gf180mcu-pdk-announce>`_
[`join link <https://groups.google.com/forum/#!forum/gf180mcu-pdk-announce/join>`_].

See both the `Known Issues <docs/known_issues.rst>`_ section and the `GF180MCU PDK GitHub issue list <https://github.com/google/gf180mcu-pdk/issues>`_ to get more detailed information around currently known issues.

GF180MCU Process Node
=====================


Prerequisites
=============

At a minimum:

-  Git 2.35+
-  Python 3.6+

On Ubuntu, simply
------------------

``apt install -y build-essential virtualenv python3``

Building the documentation
==========================

To build documentation locally, you could use the following commands:

.. code:: bash

   # Download the repository
   git clone https://github.com/google/gf180mcu-pdk.git
   cd gf180mcu-pdk/docs

   # Create a Python virtual environment and install requirements into it.
   virtualenv env --python=python3
   . env/bin/activate
   pip install -r requirements.txt

   # Build the documentation
   make html

Support
=======

Like many open source projects there are multiple ways to get support on the GF180MCU PDK.

GlobalFoundries has created a Market Partner Ecosystem to be able to provide support from design through back end package and test.  If you are interested in getting additional support through the ASIC development process, reach out to GlobalFoundries using the information in the `Contacting GlobalFoundries`_ section below.

There is also a `users mailing list  <https://groups.google.com/forum/#!forum/gf180mcu-pdk-users>`_ [`join link <https://groups.google.com/forum/#!forum/gf180mcu-pdk-users/join>`_] to allow like minded users of the PDK to provide support to each other.
