Hi,
I am using Virtex2Pro, and I have assigned LVDCI IO standards for all my LVCMOS receivers. I was wondering if LVDCI has any significance for inputs. For outputs it adds a series termination resistor, what does it do for inputs? Does it add parallel resistor?? The user guide does not state anything clearly.

Goli,
LVDCI does nothing for inputs. LVDCI is series terminated only at the drivers.
HSTL_DCI, SSTL_DCI use parallel termination at the receiver.
See the user's guide.
