How to choose a specific PLL

Hi foks,  

 

I am using 2 plls in CycloneIII.  

 

They are all fed by one common clock source. My question is, how to tell Quartus to use specific PLLs for my application. 

 

For example, PLL3 for one of my pll_inst, and PLL4 for another.  

 

 

Thanks, 

 

Frank

Make an Assignment in the assignment Editor.

The assignment Avatar referred to is in the Assignment Editor Category list under "All --> Locations --> PLL". I usually use a PLL output node name in these assignments, but I think you can also use the PLL hierarchy name like pll:pll_inst|altpll:altpll_component.
