This example shows:
- A configuration-chain flip-flop which is defined in a Verilog netlist ``ccff.v`` and a SPICE netlist ``ccff.sp``
- The flip-flop has a global clock port, ``CK``, which will be wired a global programming clock
.. note::
The output ports of the configuration flip-flop must follow a fixed sequence in definition:
- The first output port **MUST** be the data output port, e.g., ``Q``.
- The second output port **MUST** be the **inverted** data output port, e.g., ``QN``.
Configuration-chain Flip-flop with Configure Enable Signals
```````````````````````````````````````````````````````````
Configuration chain could be built with flip-flops with outputs that are enabled by specific signals.
Consider the example in :numref:`fig_ccff_config_chain_config_enable`, the flip-flop has
- a configure enable signal ``CFG_EN`` to release the data output ``Q`` and ``QN``
- a pair of data outputs ``Q`` and ``QN`` which are controlled by the configure enable signal ``CFG_EN``
- a regular data output ``SCAN_Q`` which outputs registered data

The output ports of the configuration flip-flop must follow a fixed sequence in definition:
- The first output port **MUST** be the regular data output port, e.g., ``SCAN_Q``.
- The second output port **MUST** be the **inverted** data output port which is activated by the configure enable signal, e.g., ``QN``.
- The second output port **MUST** be the data output port which is activated by the configure enable signal, e.g., ``Q``.
Configuration-chain Flip-flop with Scan Input
`````````````````````````````````````````````
Configuration chain could be built with flip-flops with a scan chain input .
Consider the example in :numref:`fig_ccff_config_chain_scan_capable`, the flip-flop has
- an additional input ``SI`` to enable scan-chain capabaility
- a configure enable signal ``CFG_EN`` to release the data output ``Q`` and ``QN``
- a pair of data outputs ``Q`` and ``QN`` which are controlled by the configure enable signal ``CFG_EN``
- a regular data output ``SCAN_Q`` which outputs registered data
