Hi @MRigh​

PLL unused pins can be connected to GND. Ref page no:4

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/max-10/pcg-01018.pdf

And please note, if you are not using the analog feature in Max 10, still needed power to these blocks by VCCA. and VCCD_PLL Page no:15

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/max-10/pcg-01018.pdf

But, if you using the PLL IP, the whole PLL IP block will not be used.

But cannot say the power to VCO is completely cutoff.
