As an added convenience, the BUFGP can be used to
instantiate a high fanout clock input. The BUFGP symbol
represents a combination of the LVTTL IBUFG and BUFG
symbols, such that the output of the BUFGP can connect
directly to the clock pins throughout the design.
Unlike previous architectures, the Virtex-E BUFGP symbol
can only be placed in a global clock pad location. The LOC
property can specify a location for the BUFGP.
OBUF
An OBUF must drive outputs through an external output
port. The generic output buffer (OBUF) symbol appears in
The extension to the base name defines which I/O standard
the OBUF uses. With no extension specified for the generic
OBUF symbol, the assumed standard is slew rate limited
LVTTL with 12 mA drive strength.
The LVTTL OBUF additionally can support one of two slew
rate modes to minimize bus transients. By default, the slew
rate for each output buffer is reduced to minimize power bus
transients when switching non-critical signals.
LVTTL output buffers have selectable drive strengths.
The format for LVTTL OBUF symbol names is as follows.
OBUF_<slew_rate>_<drive_strength>
<slew_rate>
is
either
F
(Fast),
or
S
(Slow)
and
<drive_strength> is specified in milliamps (2, 4, 6, 8, 12, 16,
or 24).

The Virtex-E series supports eight banks for the HQ and PQ
packages. The CS packages support four VCCO banks.
OBUF placement restrictions require that within a given
VCCO bank each OBUF share the same output source drive
voltage. Input buffers of any type and output buffers that do
not require VCCO can be placed within any VCCO bank.
Table 20 summarizes the Virtex-E output compatibility
requirements. The LOC property can specify a location for
the OBUF.
OBUFT
The generic 3-state output buffer OBUFT, shown in
Figure 41, typically implements 3-state outputs or bidirec-
tional I/O.
The extension to the base name defines which I/O standard
OBUFT uses. With no extension specified for the generic
OBUFT symbol, the assumed standard is slew rate limited
LVTTL with 12 mA drive strength.

Output Standards Compatibility
Requirements
Rule 1
Only outputs with standards that share compatible
VCCO can be used within the same bank.
Rule 2
There are no placement restrictions for outputs
with standards that do not require a VCCO.
