Specify clock frequency for CycloneII FPGA

--- Quote Start ---

So there is a clock defined and you should be able to see this assigned to a pin on your FPGA.

You can input a lower clock frequency to this pin if you like.

No you can't. I remember, that changjianchun is actually using a Cyclone II Starter Board (he reported in a different thread before), and the said CLOCK_50 is wired to a 50 MHz clock oscillator. The 10 Mhz setting in timing analysis isn't according to the real hardware.

The obviously required method is using a clock divider with a respective large ratio to get a visible count frequency.
