Which Cyclone II board?
Does it have say four push buttons or dip switches?
Use the attached file (rename it to have the .vhd extension), attach four push buttons to the inputs, and the outputs to the seven segment display (the comments in the file show which bits are which).
Now, when you press the buttons, the SSD will show you the corresponding hex number.
Your next task is to create a counter. Make the counter width wide enough so that the four MSBs change about once per second. Connect those MSBs to your hex display, and you will see it count.
Enjoy!
