Description
The XCR3064A CPLD (Complex Programmable Logic
Device) is the second in a family of CoolRunner™ CPLDs
from Xilinx. These devices combine high speed and zero
power in a 64 macrocell CPLD. With the FZP design tech-
nique, the XCR3064A offers true pin-to-pin speeds of 7.5
ns, while simultaneously delivering power that is less than
100
µ
A at standby without the need for "turbo bits" or other
power down schemes. By replacing conventional sense
amplifier methods for implementing product terms (a tech-
nique that has been used in PLDs since the bipolar era)
with a cascaded chain of pure CMOS gates, the dynamic
power is also substantially lower than any competing
CPLD. These devices are the first TotalCMOS PLDs, as
they use both a CMOS process technology
and
the pat-
ented full CMOS FZP design technique.
The Xilinx FZP CPLDs utilize the patented XPLA
(eXtended Programmable Logic Array) architecture. The
XPLA architecture combines the best features of both PLA
and PAL type structures to deliver high speed and flexible
logic allocation that results in superior ability to make
design changes with fixed pinouts. The XPLA structure in
each logic block provides a fast 7.5 ns PAL path with five
dedicated product terms per output. This PAL path is joined
by an additional PLA structure that deploys a pool of 32
product terms to a fully programmable OR array that can
allocate the PLA product terms to any output in the logic
block. This combination allows logic to be allocated effi-
ciently throughout the logic block and supports as many as
37 product terms on an output. The speed with which logic
is allocated from the PLA array to an output is only 1.5 ns,
regardless of the number of PLA product terms used, which
results in worst case t
PD
's of only 9.0 ns from any pin to any
other pin. In addition, logic that is common to multiple out-
puts can be placed on a single PLA product term and
shared across multiple outputs via the OR array, effectively
increasing design density.
The XCR3064A CPLDs are supported by industry standard
CAE tools (Cadence/OrCAD, Exemplar Logic, Mentor, Syn-
opsys, Synario, Viewlogic, and Synplicity), using text
(ABEL, VHDL, Verilog) and/or schematic entry. Design ver-
ification uses industry standard simulators for functional
and timing simulation. Development is supported on per-
sonal computer, Sparc, and HP platforms. Device fitting
uses a Xilinx developed tool, XPLA Professional (available
on the Xilinx web site).
