Dynamic counter values for PLL

Ok... Thanks.

I had a look at the megafunction user guide for the reconfiguration of the PLL and at the application note on how to implement the reconfigurable PLL on the Stratix II, but It is still not very clear to me.

I can reprogram the N and M factors in real time by using the scan shift register.

This one is loaded via a MIF configuration file, so I have to precompile all the different frequencies in advance to be able to load them during run time?

So the only way I can reprogram the PLL is by using the quartus II software to load the new configuration?
