Building example designs
========================

Before building any example, set the installation directory to match what you
set it to earlier, for example:

.. code-block:: bash
   :name: export-install-dir

   export INSTALL_DIR=~/opt/symbiflow

Select your fpga family:

.. tabs::

   .. group-tab:: Artix-7

      .. code-block:: bash
         :name: fpga-fam-xc7

         FPGA_FAM="xc7"

   .. group-tab:: EOS S3

      .. code-block:: bash
         :name: fpga-fam-eos-s3

         FPGA_FAM="eos-s3"

Next, prepare the enviroment:

.. code-block:: bash
   :name: conda-prep-env

   export PATH="$INSTALL_DIR/$FPGA_FAM/install/bin:$PATH";
   source "$INSTALL_DIR/$FPGA_FAM/conda/etc/profile.d/conda.sh"

Finally, enter your working Conda enviroment:

.. code-block:: bash
   :name: conda-act-env

   conda activate $FPGA_FAM

.. note::

   If you don't know how to upload any of the following examples onto your
   development board, please refer to the Running examples section.
