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 environment:
.. tabs::
.. group-tab:: Artix-7
.. code-block:: bash
:name: conda-prep-env-xc7
export PATH="$INSTALL_DIR/$FPGA_FAM/install/bin:$PATH";
source "$INSTALL_DIR/$FPGA_FAM/conda/etc/profile.d/conda.sh"
.. group-tab:: EOS S3
.. code-block:: bash
:name: conda-prep-env-eos-s3
export PATH="$INSTALL_DIR/$FPGA_FAM/quicklogic-arch-defs/bin:$PATH";
source "$INSTALL_DIR/$FPGA_FAM/conda/etc/profile.d/conda.sh"
Finally, enter your working Conda environment:
.. code-block:: bash
:name: conda-act-env
conda activate $FPGA_FAM
.. tip::
You will need to run the commands for setting the path and source of your conda environment
each time you open a new terminal. You will also need to activate the Conda environment for
your hardware before you attempt to build your designs. It might be a good idea to add the
above commands to your ``.bashrc`` either as default commands that run each time you open a
new terminal or aliases to save yourself some repetitive typing.
.. 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.
Xilinx 7-Series
---------------
Enter the directory that contains examples for Xilinx 7-Series FPGAs:
.. code-block:: bash
:name: enter-dir-xc7
cd xc7
.. jinja:: xc7_counter_test
:file: templates/example.jinja
.. jinja:: xc7_picosoc_demo
:file: templates/example.jinja
.. jinja:: xc7_litex_demo
:file: templates/example.jinja
.. jinja:: xc7_linux_litex_demo
:file: templates/example.jinja
Additional Examples
-------------------
In addition to the designs we have gone over here, you can also find several other exciting designs
for the basys3 board in the additional_examples directory:
.. code-block:: bash
:name: additional_examples
cd additional_examples
QuickLogic EOS S3
-----------------
Enter the directory that contains examples for QuickLogic EOS S3:
.. code-block:: bash
:name: enter-dir-eos-s3
cd eos-s3
.. jinja:: eos-s3_btn_counter
:file: templates/example.jinja
