Using SelectI/O
The Virtex-E FPGA series includes a highly configurable,
high-performance I/O resource, called SelectI/O to pro-
vide support for a wide variety of I/O standards. The
SelectI/O resource is a robust set of features including pro-
grammable control of output drive strength, slew rate, and
input delay and hold time. Taking advantage of the flexibility
and SelectI/O features and the design considerations
described in this document can improve and simplify sys-
tem level design.
Introduction
As FPGAs continue to grow in size and capacity, the larger
and more complex systems designed for them demand an
increased variety of I/O standards. Furthermore, as system
clock speeds continue to increase, the need for high perfor-
mance I/O becomes more important. While chip-to-chip
delays have an increasingly substantial impact on overall
system speed, the task of achieving the desired system per-
formance becomes more difficult with the proliferation of
low-voltage I/O standards.
SelectI/O, the revolutionary input/output resource of Vir-
tex-E devices, has resolved this potential problem by provid-
ing a highly configurable, high-performance alternative to
the I/O resources of more conventional programmable
devices. The Virtex-E SelectI/O features combine the flexi-
bility and time-to-market advantages of programmable logic
with the high performance previously available only with
ASICs and custom ICs.
Each SelectI/O block can support up to 20 I/O standards.
Supporting such a variety of I/O standards allows the support
of a wide variety of applications, from general purpose stan-
dard applications to high-speed low-voltage memory busses.
SelectI/O blocks also provide selectable output drive
strengths and programmable slew rates for the LVTTL out-
put buffers, as well as an optional, programmable weak
pull-up, weak pull-down, or weak “keeper” circuit ideal for
use in external bussing applications.
Each input/output block (IOB) includes three registers, one
each for the input, output, and 3-state signals within the
IOB. These registers are optionally configurable as either a
D-type flip-flop or as a level sensitive latch.
The input buffer has an optional delay element used to guar-
antee a zero hold time requirement for input signals regis-
tered within the IOB.
The Virtex-E SelectI/O features also provide dedicated
resources for input reference voltage (VREF) and output
source voltage (VCCO), along with a convenient banking
system that simplifies board design.
By taking advantage of the built-in features and wide variety
of I/O standards supported by the SelectI/O features, sys-
tem-level design and board design can be greatly simplified
and improved.
