Building the examples

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

export INSTALL_DIR=~/opt/symbiflow

and prepare the environment:

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:

pushd eos-s3/btn_counter && make && popd
