I like to program a simple D flip-flop with an asynchronous reset. It requires a Clock input.
I'm using a Cyclone II device. Shall I use the pin CLOCK_50 as the Clock?
Is there any example of how to use the clock?

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.

Hi,
Are you trying to create a design on the Quartus software? And are you using a devkit?

I just like to do a simple testing on how to configure Clock for a D flip-flop on FGPA board - Cyclone II family, device name EP2C20F484C7
Any idea how to configure clock?

Hi,
I assume you're able to write the RTL code and that you're using this development board: https://cs.colby.edu/courses/F22/cs232-labs/DE1_User_Manual.pdf
From your RTL code, you probably have an input clock signal, assign this to the PIN_L1 on Pin Planner, you may find this helpful: https://www.youtube.com/watch?v=XH4OajcYYjA
