SelectIO Signal Standards
The Spartan-3E I/Os feature inputs and outputs that sup-
port a wide range of I/O signaling standards
Table
differential pairs to support any of the differential signaling
standards
To define the I/O signaling standard in a design, set the
IOSTANDARD attribute to the appropriate setting. Xilinx
provides a variety of different methods for applying the
IOSTANDARD for maximum flexibility. For a full description
of different methods of applying attributes to control
IOSTANDARD, refer to
straints” in the Xilinx Software Manuals and Help.
Spartan-3E FPGAs provide additional input flexibility by
allowing I/O standards to be mixed in different banks. For a
particular V
IOSTANDARDs that can be combined and if the IOSTAN-
DARD is supported as an input only or can be used for both
inputs and outputs.
