Dedicated clock pin on DE2

--- Quote Start ---

Is anything else for configuration to use this for the PLL?

I mean, I've created a PLL with the megafunction where do I tell it to use CLK7 or its just by setting the PLL clockin port to CLOCK_EXT in the pin planer?

You can call the clock port/net anything you like, just so long as you set the pin to P26. For example, I call it clk_sma in my top-level design file.

You then connect that net name as the clock input to your PLL megafunction instance.

I would recommend creating a counter and use it to blink an LED once per second. If you have the PLL configured correctly, then it'll be pretty obvious.

This thread:

has an example zip file called de2_basic.zip. Download it and follow the instructions. It doesn't have a PLL in the example, but you could add it easily enough.
