BiDirectional Differential IO in EDK

Hi all,

Can anybody tell me how to instantiate biderectional differential IO in EDK?  I have a custom IP core which I want to connect to another board via a bunch of differential pairs, and I want to select input or output with a jumper.  I know how to do single-ended bidirectional in EDK, and I know how to do differential bidirectional in HDL, but how do I tell EDK to instantiate the IOBUFDS buffers at the top level?  Chip is a Virtex 6 CX130T; I'm using ISE/EDK 13.4

 

Thanks for any help

 

Rick
