How to use CLOCK_50 on Cyclone II device

Hello,
there's no Cylone II pin named CLOCK_50, you are apparently asking about a specific development board. Which one?
Generally, you should use a global clock network to clock your DFF, either fed by a clock input or a PLL output. There are surely demonstration projects shipped with your development board.

    The device is EP2C20F484C7.

    Can you share any link or documentation on how to use a global clock for the D flip-flop please?

    Thank you.
