pll fpga

hi all,
As all we know, now a days there are PLL included in almost all FPGA. I'm keen to know whether we (a programmer ) can select a perticular PLL for his application like clk synchronoization, or a tool itself does this task wherever it is required without informing to user....
The other way arround if i Know at this perticular stage/ location of circuit/logic i should put a PLL ... .in this case can we user PLL resided in FPGA selectively....
or there is no as such option there....
Pls let me know...
Thanking you.:idea:
 

Re: Use of PLL in FPGA

You usually generate the PLL as you would any other core, and instantiate it in your netlist. When you generate it, you can select your output frequencies, multipliers and dividers, etc.
