Getting SymbiFlow
|
|
=================
|
|
|
|
This section describe how to install SymbiFlow and setup a fully working
|
|
enviroment to later build example desings.
|
|
|
|
Prerequisites
|
|
-------------
|
|
|
|
To be able to follow through this tutorial, install the following software:
|
|
|
|
.. tabs::
|
|
|
|
.. group-tab:: Ubuntu
|
|
|
|
.. code-block:: bash
|
|
:name: install-reqs-ubuntu
|
|
|
|
apt update -y
|
|
apt install -y git wget xz-utils
|
|
|
|
.. group-tab:: CentOS
|
|
|
|
.. code-block:: bash
|
|
:name: install-reqs-centos
|
|
|
|
yum update -y
|
|
yum install -y git wget which xz
|
|
|
|
|
|
Next, clone the SymbiFlow examples repository and enter it:
|
|
|
|
.. code-block:: bash
|
|
:name: get-symbiflow
|
|
|
|
git clone https://github.com/SymbiFlow/symbiflow-examples
|
|
cd symbiflow-examples
|
|
|
|
Toolchain installation
|
|
----------------------
|
|
|
|
Now we are able to install the SymbiFlow toolchain. This procedure is divided
|
|
into three steps:
|
|
|
|
- installing the Conda package manager,
|
|
- choosing an installation directory,
|
|
- downloading the architecture definitions and installing the toolchain.
|
|
|
|
Conda
|
|
~~~~~
|
|
|
|
Download Conda installer script:
|
|
|
|
.. code-block:: bash
|
|
:name: wget-conda
|
|
|
|
wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh -O conda_installer.sh
|
|
|
|
Choose the install directory
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The install directory can either be in your home directory
|
|
such as ``~/opt/symbiflow`` or in a system directory such as ``/opt/symbiflow``.
|
|
If you choose a system directory, you will need root permission to perform the installation,
|
|
and so you will need to add some ``sudo`` commands to the instructions below.
|
|
|
|
.. code-block:: bash
|
|
:name: conda-install-dir
|
|
|
|
export INSTALL_DIR=~/opt/symbiflow
|
|
|
|
Toolchain
|
|
~~~~~~~~~
|
|
|
|
Select your target FPGA family:
|
|
|
|
.. tabs::
|
|
|
|
.. group-tab:: Artix-7
|
|
|
|
.. code-block:: bash
|
|
:name: fpga-fam-xc7
|
|
|
|
export FPGA_FAM=xc7
|
|
|
|
.. group-tab:: EOS S3
|
|
|
|
.. code-block:: bash
|
|
:name: fpga-fam-eos-s3
|
|
|
|
export FPGA_FAM=eos-s3
|
|
|
|
Next, setup Conda and your system's enviroment:
|
|
|
|
.. code-block:: bash
|
|
:name: conda-setup
|
|
|
|
bash conda_installer.sh -u -b -p $INSTALL_DIR/$FPGA_FAM/conda;
|
|
source "$INSTALL_DIR/$FPGA_FAM/conda/etc/profile.d/conda.sh";
|
|
conda env create -f $FPGA_FAM/environment.yml
|
|
|
|
Download architecture definitions:
|
|
|
|
.. tabs::
|
|
|
|
.. group-tab:: Artix-7
|
|
|
|
.. code-block:: bash
|
|
:name: download-arch-def-xc7
|
|
|
|
mkdir -p $INSTALL_DIR/xc7/install
|
|
wget -qO- https://storage.googleapis.com/symbiflow-arch-defs/artifacts/prod/foss-fpga-tools/symbiflow-arch-defs/continuous/install/112/20201208-080919/symbiflow-arch-defs-install-7c1267b7.tar.xz | tar -xJC $INSTALL_DIR/xc7/install
|
|
wget -qO- https://storage.googleapis.com/symbiflow-arch-defs/artifacts/prod/foss-fpga-tools/symbiflow-arch-defs/continuous/install/112/20201208-080919/symbiflow-arch-defs-xc7a50t_test-7c1267b7.tar.xz | tar -xJC $INSTALL_DIR/xc7/install
|
|
wget -qO- https://storage.googleapis.com/symbiflow-arch-defs/artifacts/prod/foss-fpga-tools/symbiflow-arch-defs/continuous/install/112/20201208-080919/symbiflow-arch-defs-xc7a100t_test-7c1267b7.tar.xz | tar -xJC $INSTALL_DIR/xc7/install
|
|
wget -qO- https://storage.googleapis.com/symbiflow-arch-defs/artifacts/prod/foss-fpga-tools/symbiflow-arch-defs/continuous/install/112/20201208-080919/symbiflow-arch-defs-xc7z010_test-7c1267b7.tar.xz | tar -xJC $INSTALL_DIR/xc7/install
|
|
|
|
.. group-tab:: EOS-S3
|
|
|
|
.. code-block:: bash
|
|
:name: download-arch-def-eos-s3
|
|
|
|
wget -qO- https://quicklogic-my.sharepoint.com/:u:/p/kkumar/EWuqtXJmalROpI2L5XeewMIBRYVCY8H4yc10nlli-Xq79g?download=1 | tar -xJ -C $INSTALL_DIR/eos-s3/
|
|
|
|
If the above commands exited without errors, you have successfuly installed and configured your working enviroment.
|
|
|
|
Build Example Designs
|
|
---------------------
|
|
|
|
With the toolchain installed, you can build the example designs.
|
|
The example designs are provided in separate directories:
|
|
|
|
* ``xc7`` directory for the Artix-7 devices
|
|
* ``eos-s3`` directory for the EOS S3 devices
|
