Is there no power supply pin VCCP in 10ax115?

Hi Niko

While I am still having issue opening the .OLB file, let me put my comment as follow.

For 1st Question, referring to the pin list below:

and pin connection guideline below:

VCCP and VCCA_pll need to be connected

For 2nd question, referring to pin connection guideline above:

"If all of the transceivers, fPLLs, and IOPLLs on a side are not used, then the VCCT_GXB power rails on that side can be tied to GND to save power regardless of whether they are an inner or outer bank."

"VCCH_GXBR power rails can be tied to GND to save power if all of the transceivers, fPLLs, and IOPLLs on that side are not used."

Since you are using the IOPLL, you need to connect those pins.

Thanks.
