nMigen requires Python 3.6; it works on CPython_ 3.6 (or newer), and works faster on PyPy3.6_ 7.2 (or newer).
-Simulating nMigen code requires no additional software. However, a waveform viewer like GTKWave_ is invaluable for debugging.
+For most workflows, nMigen requires Yosys_ 0.9 (or newer). A compatible version of Yosys is distributed via PyPI_ for most popular platforms.
-Converting nMigen code to Verilog requires Yosys_ 0.9 (or newer).
+Simulating nMigen code requires no additional software. However, a waveform viewer like GTKWave_ is invaluable for debugging.
-Synthesizing, placing and routing an nMigen design for an FPGA requires Yosys_ 0.9 (or newer), as well as the FPGA family specific toolchain.

Installing prerequisites
========================
-... on Windows
---------------
-
-.. todo::
+.. content-tabs::
- Determine what's appropriate here (do we put Python in PATH? what about Yosys? is there something better than GTKWave? do we just give up and suggest WSL?)
+ .. tab-container:: windows
+ :title: Windows
+ `Install Python <python:using-on-windows>`_, either from Windows Store or using the full installer. If using the full installer, make sure to install a 64-bit version of Python.
-... on Debian Linux
--------------------
+ `Download GTKWave`_, either win32 or win64 binaries. GTKWave does not need to be installed; it can be unpacked to any convenient location and run from there.
-nMigen works on Debian 10 or newer. The required version of Yosys is available in the main repository since Debian 11, but requires the Backports_ repository on Debian 10. Run:
+ .. _Download GTKWave: https://sourceforge.net/projects/gtkwave/files/
-.. note: debian 10 provides: python3 3.7.3, yosys 0.8 (yosys 0.9 in backports)
-.. note: debian 11 provides: python3 3.8.2, yosys 0.9
+ .. tab-container:: macos
+ :title: macOS
-.. code-block:: shell
+ Install Homebrew_. Then, install Python and GTKWave by running:
- $ sudo apt-get install python3-pip yosys gtkwave
+ .. code-block:: console
-.. _Backports: https://wiki.debian.org/Backports
+ $ brew install python gtkwave
+ .. _Homebrew: https://brew.sh
-... on Ubuntu Linux
--------------------
+ .. tab-container:: linux
+ :title: Linux
-nMigen works on Ubuntu 20.04 LTS or newer.
+ .. rubric:: Debian-based distributions
-.. note: ubuntu 20.04 provides: python3 3.8.2, yosys 0.9
+ Install Python and GTKWave by running:
-.. code-block:: shell
+ .. code-block:: console
- $ sudo apt-get install python3-pip yosys gtkwave
+ $ sudo apt-get install python3-pip gtkwave
+ On architectures other than x86_64 and AArch64, install Yosys by running:
-... on macOS
-------------
+ .. code-block:: console
-nMigen works best with Homebrew_. Run:
+ $ sudo apt-get install yosys
-.. code-block:: shell
+ If Yosys 0.9 (or newer) is not available, `build Yosys from source`_.
- $ brew install python yosys gtkwave
+ .. rubric:: Other distributions
-.. _Homebrew: https://brew.sh
+ Install Python and GTKWave from the package repository of your distribution.
+ On architectures other than x86_64 and AArch64, install Yosys from the package repository of your distribution.
-... on other platforms
-----------------------
+ If Yosys 0.9 (or newer) is not available, `build Yosys from source`_.
-Refer to the `Yosys README`_ for detailed build instructions.

Installing nMigen
=================
The latest release of nMigen should work well for most applications. A development snapshot---any commit from the ``master`` branch of nMigen---should be similarly reliable, but is likely to include experimental API changes that will be in flux until the next release. With that in mind, development snapshots can be used to try out new functionality or to avoid bugs fixed since the last release.
