Yes, that's the correct way to do it. Hook up a design input pin to the PLL
input, then assign that input to a clock I/O.

I think you should not use atlpll,and you should app the megafunctio
to implement your project

The mega function created has a pin called input (or similar). You simply
connect this to a device pin, and then assign the location you need for the
CLKn pin.

Hi all,
I'm using a cyclone EP1C6 Q240 and want to instanciate a pll, but using
the PLL2 (input are CLK2 and CLK3). My problem is that with the design
assistant, i can create a macro-function called altpll, but i can't
choose the input i want (clk2, on pin 153 of EP1C6Q240 ).
how should i do ?
regards,
