- ``type="ccff|ff"`` Specify the type of a flip-flop. ``ff`` is a regular flip-flop while ``ccff`` denotes a configuration-chain flip-flop
.. note:: A flip-flop should have three types of ports, ``input``, ``output`` and ``clock``.
.. note:: A flip-flop should at least have three types of ports, ``input``, ``output`` and ``clock``.
.. note:: If the user provides a customized Verilog/SPICE netlist, the bandwidth of ports should be defined to the same as the Verilog/SPICE netlist.
