Hi, Neil,

"Has anyone tried using tristate inout pins for I/O."
Yes, I did a module with a tristate inout. What I did is just instance a
"iobuf" and it works without ISE automatically adding I/O buffer.

Has anyone tried using tristate inout pins for I/O.  I am working on a 
module that does and I am having some trouble.  In order to place the 
tristates in the modules it says I have place dummy tbufs in the context of 
the module attached to the OBUF of the pins.  What is a dummy tbuf?  Also, 
is it better to place the tristate logic inside or outside the 
reconfigurable module?  

Neil
