OpenFPGA allows users to define it a mode is packable for VPR.
By default, the packable is set to ``true``.
OpenFPGA allows users to define it a mode is disabled for VPR packer.
By default, the ``disable_packing`` is set to ``false``.
This is mainly used for the mode that describes the physical implementation, which is typically not packable. Disable it in the packing and signficantly accelerate the packing runtime.
.. note:: Once a mode is set to unpackable, its child modes will be unpackable as well.
.. note:: Once a mode is disabled in packing, its child modes will be disabled as well.
