+- ``default_val=""`` define if the default value for the global port when initialized in testbenches. Valid values are either ``0`` or ``1``. For example, the default value of an active-high reset pin is ``0``, while an active-low reset pin is ``1``.

A more illustrative example:
:numref:`fig_global_tile_ports` illustrates the difference between the global ports defined through ``circuit_model`` and ``tile_annotation``.
