Taking input in FPGA through ADC.

[Knight_Rider]

Hello,

I am beginner in FPGA and currently working on CMOD A7-35T. I want to use inbuilt ADC of the board. 

My requirement is to sense analog signal coming from voltage sensor (scaled to 3.3V max) and use digital conversion of it for further work. I have gone through ADC manual provided by xilink. There are so many other parameters this ADC can be used to detect and also I found that document really confusing.  Can someone please explain what is protocol for interfacing this ADC so that my goal of sensing analog signal can be achieved. Where can I find this digital output after giving analog signal.

 

Thank you.

Xilinx has a few application notes for using the XADC feature of its Series 7 FPGA devices. Yes, it is complex.

The first question to ask is what method of FPGA design flow are your using? Any answer will be different for HDL or block diagram flow.

Thanks for reply.

I am using VERILOG coding language on VIVADO software.
