High Speed SelectIO Wizard how to configure all 24Pairs as differential Data Pins


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?


The Wizard should allow 24 differential pairs when the CLK Source is PLL and the CLK Scheme is not IBUF PLL.

Currently the wizard does not have an option to do this.

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.
