The High Speed SelectIO Wizard allows users to select a maximum of 23 differential pairs for data and one for the clock input.
Is there a way to use all of the 24 pairs in the BANK as Data pins?
To work around this issue you can use the High Speed SelectIO to set up everything else that is required for your interface and generate the output products.
Then replace the .XCI file with the <<component name>>.v
and other required files.
