Cyclone 10 LP unused PLL clkout signals

[PYtte]

I am reading through the "Intel® Cyclone® 10 LP Device Family Pin Connection Guidelines" and for PLL[1..4]_CLKOUTp and PLL[1..4]_CLKOUTn it just says

"When not using these pins, connect them as defined in Intel Quartus Prime software."

Can someone elaborate on this? Do I define them somewhere? Or are they defined by synthesizer?

I am only talking about them when not used of course. My initial thought it so connect them to ground.

EDIT: I see the same text for all DIFFIO_ signals as well.

Hi Peter,

- Yes, as mentioned the undefined pins will be defined automatically by Quartus when not in using. You can see the it in compilation report -- Fitter --> pin-out file.
