Clone this repository
---------------------
If you have not already done so, clone this repository and `cd` into it:
.. code:: bash
sudo apt install git
git clone https://github.com/SymbiFlow/symbiflow-examples.git && cd symbiflow-examples
Setting up the toolchain
------------------------
Choose the installation directory (see the `README <../README.rst>`_ one level up for details):
.. code:: bash
export INSTALL_DIR=~/opt/symbiflow # or somewhere else you choose
.. toolchain_include_begin_label
.. code:: bash
:name: eoss3-setup-toolchain
bash conda_installer.sh -b -p $INSTALL_DIR/eos-s3/conda
source "$INSTALL_DIR/eos-s3/conda/etc/profile.d/conda.sh"
conda env create -f eos-s3/environment.yml
conda activate eos-s3
wget -qO- https://quicklogic-my.sharepoint.com/:u:/p/kkumar/EWuqtXJmalROpI2L5XeewMIBRYVCY8H4yc10nlli-Xq79g?download=1 | tar -xJ -C $INSTALL_DIR/eos-s3/
conda deactivate
.. toolchain_include_end_label
Building the examples
---------------------
.. build_examples_include_begin_label
Before building any example, set the installation directory to match what you set it to earlier,
.. code:: bash
export INSTALL_DIR=~/opt/symbiflow
and prepare the environment:
.. code:: bash
:name: eoss3-prepare-env
export PATH="$INSTALL_DIR/eos-s3/install/bin:$PATH"
source "$INSTALL_DIR/eos-s3/conda/etc/profile.d/conda.sh"
conda activate eos-s3
To build the example, run the following command:
.. code:: bash
:name: eoss3-counter
pushd eos-s3/btn_counter && make && popd
.. build_examples_include_end_label
