Is there no power supply pin VCCP in 10ax115?

[niko]

Hi, I am using 10ax115R3F40

Question 1: I cant found VCCP and VCCa_pll pins on my sch lib downing from intel website.  Do it say that these two type pin no need connect? But it have VCCa_fpll. Is this mean vcca_fpll instead vcca_pll?

Question 2 : I dont use Tranceivers. But I use IOPLL. Can i connect  vcch_gxbl/vcch_gxbr/vcct_gxbl/vcct_gxbr to GND?

Thank you!

Hi Niko

Can you share with us the link where you downloaded those Arria 10 files? 

For Arria 10 pin connection, we shall always refer to pin connection guideline:

Thanks.

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:

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/arria-10/10ax115.pdf

and pin connection guideline below:

https://www.intel.com/content/www/us/en/programmable/documentation/wtw1404286459773.html

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.
