Hello ,Is there an overlay example which has DAC or ADC in it?
The basic overlay descibed below doesnt have any DAC and ADC like that.
Thanks.
Hi @yefj,
The baseoverlay does have ADCs and DACs on it.
There are also more overlays that include ADCs and DACs. See here RFSoC-PYNQ overlays | RFSoC-PYNQ

Hello , The overlay PDF is attached.I was told RFDC is the name of the ADC/DAC block in the FPGA used on that board.There is no such block.
Where is the ADC/DAC block?
Thanks.
It is inside of the radio hierarchy. You need to rebuild the overlay to see it completely.
Hello Mario,As you can see both in the PDF and video below the output on the right side doesnt have any radio hirarchy block.
where can i find it?
Thanks.
You just scrolled by it at 0:27.
Hello Mario Yes I saw it.However I saw another good source described in the manual below and attached link of the video.
In this AMD manual there is only a photo .How can I download the vivdo project project of this example?

We do not provide the Vivado project directly. You need to rebuild it from source.
Hello Mario,Yes I understand.So the radio block controlles the DAC and ADC.
is there some other manuals regarding how I get from this vivado overlay to actually seeing the signals on ADC of the RFsock4x2?
Thanks.
The RFSoC Book is a great way to get started. https://www.rfsocbook.com/
Hello Mario , In general we take the overlay make HDL wrapper and export it as XSA file to vitis .
What about here in this case where in the book they talk about the transition step from overlay into the PYNQ notebooks?
Thanks.
The hardware design flow does not change. You can still export the design to xsa an import it in Vitis. PYNQ will also take the xsa.

Hello Mario ,Where in the book we can see how to control the DAC given XSA of the basic overlay.
my goal is to give it a vector(Dgital data) and see the output of analog signal.
Having arbitrary waveform generator.
Thanks.
