Virtex™-E 1.8 V Field Programmable Gate Arrays
The voltage reference signal is “banked” within the Virtex-E
device on a half-edge basis such that for all packages there
are eight independent V
for a representation of the Virtex-E I/O banks. Within each
bank approximately one of every six I/O pins is automati-
cally configured as a V
amplifier input signal within a given V
external source must drive all I/O pins configured as a V
input.
IBUF placement restrictions require that any differential
amplifier input signals within a bank be of the same stan-
dard. How to specify a specific location for the IBUF via the
LOC property is described below.
Virtex-E input standards compatibility requirements.
An optional delay element is associated with each IBUF.
When the IBUF drives a flip-flop within the IOB, the delay
element by default activates to ensure a zero hold-time
requirement. The NODELAY=TRUE property overrides this
default.
When the IBUF does not drive a flip-flop within the IOB, the
delay element de-activates by default to provide higher per-
formance. To delay the input signal, activate the delay ele-
ment with the DELAY=TRUE property.

Requirements
IBUFG
Signals used as high fanout clock inputs to the Virtex-E
device should drive a global clock input buffer (IBUFG) via
an external input port in order to take advantage of one of
the four dedicated global clock distribution networks. The
output of the IBUFG should only drive a CLKDLL,

The extension to the base name determines which I/O stan-
dard is used by the IBUFG. With no extension specified for
the generic IBUFG symbol, the assumed standard is
LVTTL.

When the IBUFG symbol supports an I/O standard that
requires a differential amplifier input, the IBUFG automati-
cally configures as a differential amplifier input buffer. The
low-voltage I/O standards with a differential amplifier input
require an external reference voltage input V
The voltage reference signal is “banked” within the Virtex-E
device on a half-edge basis such that for all packages there
are eight independent V

IBUFG placement restrictions require any differential ampli-
fier input signals within a bank be of the same standard. The
LOC property can specify a location for the IBUFG.
As an added convenience, the BUFGP can be used to
instantiate a high fanout clock input. The BUFGP symbol
