 You can configure RAD-Sim for your example design simulation using the following commands executed at the ``rad-sim`` root directory (the commands use the ``mlp`` example design which can be replaced by your own design under the ``rad-flow/rad-sim/example-designs`` directory):
-    .. code-block:: bash
-        $ cd <rad_flow_root_dir>/rad-sim
-        $ python config.py mlp
-        $ cd build
-        $ cmake ..
-        $ make
