Installation
Warning
The following instructions are a work-in-progress and may not be entirely up to date.
System requirements
Torii requires Python >= 3.10, and Yosys >= 0.30 except Yosys version 0.37 due to a Verilog backend bug. Torii has been tested with CPython, but might possibly run under PyPy.
Simulating Torii code requires no additional software. However, a waveform viewer like GTKWave is invaluable for debugging.
Synthesizing, placing and routing an Torii design for an FPGA requires the FPGA family specific toolchain. See the platform specific documentation for more information regarding vendor toolchains.
Installing Prerequisites
Prior to installing Torii, you must install all of its prerequisites and requirements.
Installing Python
First off, install python and pip onto your system if the’re not there already.
Arch Linux
$ sudo pacman -S python python-pip
Other Linux
Warning
These instructions may be incorrect or incomplete!
For Debian based systems, use apt to install python3 and python3-pip
$ sudo apt install python3 python3-pip
For Fedora and other dnf based systems,
$ sudo dnf install python3 python3-pip
Windows
Warning
These instructions may be incorrect or incomplete!
Download the latest Python installer from the python downloads page.
Follow the instructions and ensure that the installer installs pip and puts the python executable in your %PATH%
Installing Yosys and GTKWave
Arch Linux
On Arch Linux and Arch-likes, you can install nightly Yosys packages which are located in the AUR with an AUR helper or using makepkg directly.
Via an AUR helper like yay
$ yay -S yosys-nightly
Via makepkg directly
$ git clone https://aur.archlinux.org/yosys-nightly.git
$ (cd yosys-nightly && makepkg -sic)
And to install GTKWave you can just install it like any normal package
$ pacman -S gtkwave
Other Linux
Warning
These instructions may be incorrect or incomplete!
With other Linux distributions, it is recommended to use the OSS Cad Suite nightly build. It provides a full environment of all the tools needed built on a nightly basis. This includes Yosys and GTKWave
Simply download the latest release for your architecture, extract it to a good home, and then add it to your $PATH
$ curl -LOJ https://github.com/YosysHQ/oss-cad-suite-build/releases/download/2024-05-04/oss-cad-suite-linux-x64-20240504.tgz
$ tar xfv oss-cad-suite-linux-x64-20240504.tgz
$ export PATH="`pwd`/oss-cad-suite/bin:$PATH"
macOS
For macOS systems, it is recommended to use the YoWASP distribution of the toolchain. However if you want to use the native tools, and you are using an Intel based Mac, then the OSS Cad Suite has nightly builds for x86_64 versions of Darwin. This includes Yosys and GTKWave
Simply download the latest release for your architecture, extract it to a good home, and then add it to your $PATH
$ curl -LOJ https://github.com/YosysHQ/oss-cad-suite-build/releases/download/2024-05-04/oss-cad-suite-darwin-x64-20240504.tgz
$ tar xfv oss-cad-suite-darwin-x64-20240504.tgz
$ export PATH="`pwd`/oss-cad-suite/bin:$PATH"
Windows
Warning
These instructions may be incorrect or incomplete!
The OSS Cad Suite has nightly builds for x86_64 versions of Windows. This includes Yosys and GTKWave
Simply download the latest release for your architecture, extract it to a good home, and then add it to your %PATH%
$ call %cd%\oss-cad-suite\environment.bat
Installing Torii
The latest release of Torii is recommended for any new projects planning to use Torii. It provides the most up-to-date stable version of the API. However, if needed, you can also install a development snapshot to get access to the bleeding-edge, however the API may be unstable.
Latest release
Linux
$ pip3 install --user --upgrade torii
macOS
$ pip install --user --upgrade torii
Windows
> pip install --upgrade torii
Development snapshot
Linux
$ pip3 install --user 'torii @ git+https://github.com/shrine-maiden-heavy-industries/torii-hdl.git'
macOS
$ pip install --user 'torii @ git+https://github.com/shrine-maiden-heavy-industries/torii-hdl.git'
Windows
> pip install "torii @ git+https://github.com/shrine-maiden-heavy-industries/torii-hdl.git"
Editable development snapshot
Linux
To install an editable development snapshot of Torii for the first time, run:
$ git clone https://github.com/shrine-maiden-heavy-industries/torii-hdl
$ cd torii-hdl
$ pip3 install --user --editable '.'
Any changes made to the torii-hdl directory will immediately affect any code that uses Torii. To update the snapshot, run:
$ cd torii-hdl
$ git pull --ff-only origin main
$ pip3 install --user --editable '.'
Run the pip3 install --editable . command each time the editable development snapshot is updated in case package dependencies have been added or changed. Otherwise, code using Torii may misbehave or crash with an ImportError.
macOS
To install an editable development snapshot of Torii for the first time, run:
$ git clone https://github.com/shrine-maiden-heavy-industries/torii-hdl
$ cd torii-hdl
$ pip install --user --editable '.'
Any changes made to the torii-hdl directory will immediately affect any code that uses Torii. To update the snapshot, run:
$ cd torii-hdl
$ git pull --ff-only origin main
$ pip install --user --editable '.'
Run the pip install --editable . command each time the editable development snapshot is updated in case package dependencies have been added or changed. Otherwise, code using Torii may misbehave or crash with an ImportError.
Windows
To install an editable development snapshot of Torii for the first time, run:
> git clone https://github.com/shrine-maiden-heavy-industries/torii-hdl
> cd torii-hdl
> pip install --editable .
