IBERT reference clocks

Hi,

 

when configuring IBERT IP core for Ultrascale GTH (1.3) I can see in the configuration gui many input reference clocks (see attachment).

 

On my custom board I have four reference clocks (one per QUAD) available.

 

What is the difference between

 

the refclks with one index

gtrefclk0_i

gtrefclk1_i

 

and those with two indices

gtrefclk00_i

gtrefclk01_i

gtrefclk_10

gtrefclk_11

?

 

Thank you for your clarification.

 

Kind regards, Noreeli
