Updating base overlay with IP block of basic input

[yefj]

Hello ,I want to input a signal to the radio IP (part of the basic overlay)PDF attached.

So I could use as DAC.Vin2_01 is the port I want to put the signal inside as shown below.
Two questions:

1.looking at the RFDC block shown below , what is the variable type that its looking for when inputing the Vin2_01?

2.Is there IP I can use to input digital data to Vin2_01?

I tried to use the constant block as shown below to input the Vin2_01 but they dont mactch.How do I make them match?

Thanks.

Vin* are special ports on the RFDC IP block that connect directly to the analog pins on the RFSoC device. You can’t connect these to anything other than the external ports in Vivado.
