Xilinx Teams With Ansoft for Faster and Easier High-Speed Printed
Circuit Board and Backplane Design 10 Gbps Interconnect Design Kit
Supports Xilinx Virtex-II Pro X Series FPGAs SAN JOSE, Calif., Oct.
25 /PRNewswire/ -- Xilinx Inc. (NASDAQ:XLNX) and Ansoft Corp.
(NASDAQ:ANST) today announced a new Gigabit Interconnect Design Kit
that allows customers to perform extremely accurate "what if"
analyses on high-speed printed circuit board (PCB) and backplane
designs. Powered with Virtex-II Pro(TM) X series FPGAs from Xilinx,
the kit enables engineers to anticipate problems early in the
design phase and predict the quality of a signal, thereby
significantly minimizing lab debug times and costly board respins.

Xilinx modular FPGA technology combined with Ansoft's simulation
expertise is required for today's devices with serial I/O speeds up
to 10 Gbps," said Dr. Larry Williams, director, Business
Development at Ansoft. "Together, Xilinx and Ansoft are leading the
industry in realizing right-the-first-time, high-speed designs."
According to Ed McGettigan, director, APD Systems Engineering at
Xilinx, "The growing popularity of FPGA platform solutions with
multi-gigabit I/O functionality has led to architectures that place
greater demands on PCB designs. Extremely accurate signal-integrity
design for proper system operation is required. The 'what-if'
analyses from Ansoft provide an extra edge relative to simulating
all circuit behavior, ensuring that our customers are making the
right decisions early in the design process." Significant signal
degradation occurs after passing through the transmission path,
including loss of signal amplitude, reduction of signal rise time
and a spreading at the zero crossings. Given this backdrop, it is
imperative to accurately model the transmission path when designing
a high-performance, high-speed, serial interconnect system to
ensure optimal performance. Xilinx teamed with Ansoft to provide
methods and guidelines for modeling high-speed interconnect.
Accurate electrical models that account for the physical effects
have been created for the Xilinx Virtex-II Pro X IC package,
microstrip and stripline transmission lines, connectors and circuit
board via using electromagnetic-field simulation. The full channel
response -- from the integrated circuit through the package, onto
the board and out the connector -- was computed using Ansoft's
Nexxim(TM), DesignerSI(TM) and HFSS(TM) for circuit, system and
electromagnetic simulation. The Gigabit Interconnect Design Kit is
based on the Xilinx MK322 Platform, the primary circuit board used
for the electrical evaluation and characterization of the
RocketIO(TM) X high-speed serial multi-gigabit transceivers in
Virtex-II Pro X FPGAs. The design kit is a virtual evaluation board
that allows PCB and backplane designers to simulate their specific
design and requirements. Because all critical variables are
parameterized, use of the design kit enables simulation of
topologies that are different from that on the MK322 board.
Combined with the Virtex-II Pro X driver and receiver models --
with programmable pre-emphasis levels, voltage swing and receive
side equalization -- this approach allows for complete virtual
prototyping of the individual channels in very-high-data-rate
systems. The kit currently supports Xilinx Virtex-II Pro X FPGAs
and is scaleable to support Virtex-4(TM) FPGAs. Parameterized
models associated with this effort have been assembled into the
design kit and are available on
http://www.gigabitbackplanedesign.com/ along with associated
presentations and white paper. About Xilinx Virtex-II Pro X FPGAs
Xilinx Virtex-II Pro X FPGAs incorporate up to 20 RocketIO
multi-gigabit transceivers, supporting operating ranges of 2.488
Gbps to 10.3125 Gbps per channel. Virtex-II Pro X FPGAs are the
first programmable ICs that can directly drive optical transceiver
OC-48 SONET compliant systems and support SONET implementation for
OC-192 data rates and above. Virtex-II Pro X FPGAs also enable new
applications, which require multiple high-speed serial channels
each running in speeds up to 10.3125 Gbps, including popular
bandwidth nodes such as 4.25 Gbps, 5 Gbps, and 6 Gbps. The 10 Gbps
transceivers, when used in multiples, support effective bandwidths
through the FPGA of more than 200 Gbps. About Virtex-4 FPGAs
Enabled by the revolutionary ASMBL (Advanced Silicon Modular Block)
architecture, Virtex-4 FPGAs deliver more options than any other
FPGA family available today. With more than 100 technical
innovations, the Virtex-4 family consists of 17 devices and three
domain-optimized platforms: Virtex-4 LX FPGAs for logic-intensive
designs, Virtex-4 SX FPGAs for high-performance signal processing,
and Virtex-4 FX FPGAs for high-speed serial connectivity and
embedded processing. A multi-platform approach makes it possible
for customers to select the optimal mix of resources for their
application to achieve the highest functionality and performance at
the lowest cost. Virtex-4 FX platform devices embed up to two
32-bit RISC PowerPC(TM) processors delivering in excess of 1300
Dhrystone MIPS along with up to four integrated 10/100/1000
Ethernet MAC cores for high-performance embedded processing
applications. A new Auxiliary Processor Unit (APU) provides an
intimate connection between the processors and the FPGA hardware
resources -- enabling a new class of flexible yet extremely
high-performance integrated software/hardware designs. FX platform
devices also include up to 24 RocketIO high-speed serial
transceivers supporting the industry's widest performance range of
622 Mbps to 11.1 Gbps for industry-leading levels of high-speed
serial performance. All key high-speed serial performance levels
are supported including 10.3125, 8.5, 6.25, 4.25, 3.125, 2.5, 1.25
and 0.622 Gbps. About Ansoft Ansoft is a leading developer of
