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.

"The 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.
