        ice40_wrapcarry [selection]

    ::

        Wrap manually instantiated SB_CARRY cells, along with their associated SB_LUT4s,
        into an internal $__ICE40_CARRY_WRAPPER cell for preservation across technology
        mapping.

        Attributes on both cells will have their names prefixed with 'SB_CARRY.' or
        'SB_LUT4.' and attached to the wrapping cell.
        A (* keep *) attribute on either cell will be logically OR-ed together.


    .. code:: yoscrypt

        -unwrap

    ::

            unwrap $__ICE40_CARRY_WRAPPER cells back into SB_CARRYs and SB_LUT4s,
            including restoring their attributes.
