Xilinx Arty US$99 FPGA board. Expert opinions please.

[sundersoft]

The FPGA on this board doesn't seem to support 6.6Gb/s GTP according to the datasheets.

The 7 series product selection guide says that the CSG324 package doesn't have any GTP transcievers. The Artix 7 datasheet says that only speed grades 2 and 3 support 6.6Gb/s for GTP.

However, the web page claims that it has four 6.6Gb/s GTP transcievers.

Is there an error on the webpage or is the datasheet wrong?

Where did you find information about GTPs on Arty board? I just searched the store page for the board and didn't find any mentions of transceivers.
They are available in CSG325 package, but not in CSG324.

If you scroll to the bottom of the hardware tab on the page, it mentions GTP tranceivers. I assume it's a mistake on the page.

Yes, I think it's a mistake on their part. There are no mentions of GTPs on Digilent's page.

I am 100% sure that they have transcievers on the FPGA die, not sure if they are connected to the package, and enev if they are they are not used on the Arty board.

Of course they are on die, but in 324 package they are not bonded out, while in 325 package they are. Go figure!

Parts without transceivers have had both no bonds attached to them, and been laser trimmed out of the power supply network so they don't consume any power. The CSG324 and CSG325 packages trade more IO for transceivers depending on ones needs.
