Virtex-5 FPGA I/O Bank Rules
All Virtex-5 FPGAs have configurable high-performance SelectIO™ drivers and receivers,
supporting a wide variety of standard interfaces. The robust feature set includes
programmable control of output strength and slew rate, and on-chip termination using
Digitally Controlled Impedance (DCI).
Each IOB contains both input, output, and 3-state SelectIO drivers. These drivers can be
configured to various I/O standards. Differential I/O uses the two IOBs grouped together
in one tile.

Each Virtex-5 FPGA I/O tile contains two IOBs, and also two ILOGIC blocks and two
OLOGIC blocks, as described in
Figure 6-2
X-Ref Target - Figure 6-2
Each IOB has a direct connection to an ILOGIC/OLOGIC pair containing the input and
output logic resources for data and 3-state control for the IOB. Both ILOGIC and OLOGIC
can be configured as ISERDES and OSERDES, respectively, as described in
Advanced SelectIO Logic
This section summarizes the general guidelines to be considered when designing with the
SelectIO resources in Virtex-5 FPGAs.
In Virtex-5 devices, with some exceptions in the center column, an I/O bank consists of 40
IOBs (20 CLBs high and a single clock region). There are always four half-sized banks
(20 IOBs) and a single configuration bank in the center column. The number of banks
