XADC Artix-7 licence

[shawnmk123]

Hello,

I'm using the XADC in Artix-7.

Please inform if this feature is free to use or is it a paid licence?

Can I use this feature by directly connecting the pins to ADxP/ADxN pins of the FPGA?

I'm building a custom FPGA board. I'm pretty new to FPGA PCB layout. Please help.

You should really learn to read and find the documentation. Install the Xilinx Document Navigator if you haven't. It makes searching for documents and topics very easy.

Here are some of the documents that tell you how to connect those pins.

XADC layout guidelines, XAPP554

Driving the XADC inputs app note XAPP795

and finally the user guide for the XADC, UG480

Oh yeah about your other question it's free, it's already built into the device (hard IP) and can even be seen to work, just by connecting the JTAG cable and opening chipscope or in Vivado opening the hardware manager. There will be a XADC already there that allows JTAG to monitor the VCCINT and die temp.
