General Description
The Quantum38K family, based on a 0.18-mm, six-layer metal
CMOS logic process, offers a wide range of solutions at very
high system performance. With devices ranging from 512 to
1536 macrocells, Quantum38K is the highest density CPLD in
the market besides Cypress's Delta39K. Specifically designed
to address high-volume communication applications, this
family also integrates Cypress's dual-port memory technology
onto a CPLD.
The architecture is based on Logic Block Clusters (LBC) that
are connected by Horizontal and Vertical (H&V) routing
channels. Each LBC features eight individual Logic Blocks
(LB). Adjacent to each LBC is a channel memory block, which
can be accessed directly from the I/O pins. These channel
memory blocks are highly configurable and can be cascaded
in width and depth. See Figure 1 for a block diagram of the
Quantum38K architecture.
All the members of the Quantum38K family have Cypress's
highly regarded In-System Reprogrammability (ISR) feature,
which simplifies both design and manufacturing flows, thereby
reducing costs. The ISR feature provides the ability to recon-
figure the devices without having design changes cause
pinout or timing changes in most cases. The Cypress ISR
function is implemented through a JTAG-compliant serial
interface. Data is shifted in and out through the TDI and TDO
pins respectively. Superior routability, simple timing, and the
ISR allows users to change existing logic designs while simul-
taneously fixing pinout assignments and maintaining system
performance.
The entire family features JTAG for ISR and boundary scan,
and is compatible with the PCI Local Bus specification,
meeting the electrical and timing requirements. The
Quantum38K family also features user programmable
bus-hold and slew rate control capabilities on each I/O pin.
AnyVolt Interface
All Quantum38K devices feature an on-chip regulator, which
accepts 3.3V or 2.5V on the V
CC
supply pins and steps it down
to 1.8V internally, the voltage level at which the core operates.
With Quantum38K's AnyVolt technology, the I/O pins can be
connected to either 1.8V 2.5V, or 3.3V. All Quantum38K
devices are 3.3V tolerant regardless of V
CCIO
or V
CC
settings.
Global Routing Description
The routing architecture of the Quantum38K is made up of
H&V routing channels. These routing channels allow signals
from each of the Quantum38K architectural components to
communicate with one another. In addition to the horizontal
and vertical routing channels that interconnect the I/O banks,
channel memory blocks, and logic block clusters, each LBC
contains a Programmable Interconnect Matrix (PIMTM), which
is used to route signals among the logic blocks.
Figure 2 is a block diagram of the routing channels that
interface within the Quantum38K architecture. The LBC is
exactly the same for every member of the Quantum38K CPLD
family.
Logic Block Cluster (LBC)
The Quantum38K architecture consists of several logic block
clusters, each of which have eight Logic Blocks (LB)
connected via a PIM, as shown in Figure 3. All LBCs interface
with each other via horizontal and vertical routing channels.

Logic Block (LB)
The logic block is the basic building block of the Quantum38K
architecture. It consists of a product term array, an intelligent
product-term allocator, and 16 macrocells.
Product Term Array
Each logic block features a 72 x 83 programmable product
term array. This array accepts 36 inputs from the PIM. These
inputs originate from device pins and macrocell feedbacks as
well as channel memory feedbacks. Active LOW and active
HIGH versions of each of these inputs are generated to create
the full 72-input field. The 83 product terms in the array can be
created from any of the 72 inputs.
Of the 83 product terms, 80 are for general-purpose use for
the 16 macrocells in the logic block. Two of the remaining three
product terms in the logic block are used as asynchronous set
and asynchronous reset product terms. The final product term
is the Product Term clock (PTCLK) and is shared by all 16
macrocells within a logic block.
Product Term Allocator
Through the product term allocator, Warp software automati-
cally distributes the 80 product terms as needed among the 16
macrocells in the logic block. The product term allocator
provides two important capabilities without affecting perfor-
mance: product term steering and product term sharing.
Product Term Steering
Product term steering is the process of assigning product
terms to macrocells as needed. For example, if one macrocell
requires ten product terms while another needs just three, the
product term allocator will "steer" ten product terms to one
macrocell and three to the other. On Quantum38K devices,
product terms are steered on an individual basis. Any number
between 1 and 16 product terms can be steered to any
macrocell.
Product Term Sharing
Product term sharing is the process of using the same product
term among multiple macrocells. For example, if more than
one function has one or more product terms in its equation that
are common to other functions, those product terms are only
programmed once. The Quantum38K product term allocator
allows sharing across groups of four macrocells in a variable
fashion. The software automatically takes advantage of this
capability so that the user does not have to intervene.
Note that neither product term sharing nor product term
steering have any effect on the speed of the product. All
steering and sharing configurations have been incorporated in
the timing specifications for the Quantum38K devices.
Macrocell
Within each logic block there are 16 macrocells. Each
macrocell accepts a sum of up to 16 product terms from the
product term array. The sum of these 16 product terms can be
output in either registered or combinatorial mode. Figure 4
displays the block diagram of the macrocell. The register can
be asynchronously preset or asynchronously reset at the
macrocell level with the separate preset and reset product
terms. Each of these product terms features programmable
polarity. This allows the registers to be preset or reset based
on an AND expression or an OR expression.
An XOR gate in the Quantum38K macrocell allows for many
different types of equations to be realized. It can be used as a
polarity mux to implement the true or complement form of an
equation in the product term array or as a toggle to turn the D
flip-flop into a T flip-flop. The carry-chain input mux allows
additional flexibility for the implementation of different types of
logic. The macrocell can utilize the carry chain logic to
