The LVTTL OBUFT 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.

strengths.
The format for LVTTL OBUFT symbol names is as follows.
OBUFT_<slew_rate>_<drive_strength>
<slew_rate> can be either F (Fast), or S (Slow) and
<drive_strength> is specified in milliamps (2, 4, 6, 8, 12, 16,
or 24).
The following list details variations of the OBUFT symbol.

The Virtex-E series supports eight banks for the HQ and PQ
packages. The CS package supports four VCCO banks.
The SelectI/O OBUFT placement restrictions require that
within a given VCCO bank each OBUFT share the same out-
put source drive voltage. Input buffers of any type and out-
put buffers that do not require VCCO can be placed within
the same VCCO bank.
The LOC property can specify a location for the OBUFT.
3-state output buffers and bidirectional buffers can have
either a weak pull-up resistor, a weak pull-down resistor, or
a weak “keeper” circuit. Control this feature by adding the
appropriate symbol to the output net of the OBUFT (PUL-
LUP, PULLDOWN, or KEEPER).
The weak “keeper” circuit requires the input buffer within the
IOB to sample the I/O signal. So, OBUFTs programmed for
an I/O standard that requires a VREF have automatic place-
ment of a VREF in the bank with an OBUFT configured with
a weak “keeper” circuit. This restriction does not affect most
circuit design as applications using an OBUFT configured
with a weak “keeper” typically implement a bidirectional I/O.
In this case the IBUF (and the corresponding VREF) are
explicitly placed.
The LOC property can specify a location for the OBUFT.
IOBUF
Use the IOBUF symbol for bidirectional signals that require
both an input buffer and a 3-state output buffer with an
active high 3-state pin. The generic input/output buffer
IOBUF appears in Figure 42.
The extension to the base name defines which I/O standard
the IOBUF uses. With no extension specified for the generic
IOBUF symbol, the assumed standard is LVTTL input buffer
and slew rate limited LVTTL with 12 mA drive strength for
the output buffer.
The LVTTL IOBUF 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 bidirectional buffers have selectable output drive
strengths.
The format for LVTTL IOBUF symbol names is as follows.
IOBUF_<slew_rate>_<drive_strength>
<slew_rate> can be either F (Fast), or S (Slow) and
<drive_strength> is specified in milliamps (2, 4, 6, 8, 12, 16,
or 24).
