XILINX DEMONTRATES 7x SIGNAL INTEGRITY ADVANTAGE OF VIRTEX-4 FPGAs TO ENGINEERS AROUND THE WORLD

Xilinx, Inc. (NASDAQ: XLNX) today announced that its worldwide RocketLabs have been outfitted with signal integrity demo boards highlighting the distinct signal integrity advantage of the Xilinx Virtex -4 multi-platform FPGA family over competing FPGAs. Xilinx RocketLabs provides systems designers free access to high-speed design equipment, evaluation boards, applications expertise and specialized training. New signal integrity demo boards, lab measurements and simulations conducted by renowned signal integrity expert, Dr. Howard Johnson, clearly illustrate that the advanced packaging technology of Virtex-4 FPGAs provides up to seven times less crosstalk compared to competing 90nm FPGAs. Designers can subsequently take advantage of this enhanced signal integrity for every high-speed application, including commonly used memory interfaces.

Today's high-speed designs routinely have hundreds of I/Os, with buses greater than 32 bits, 300+ Mbps bandwidth and shrinking timing margins. At these data rates, practically every design has inductive crosstalk and simultaneous switching output noise that can have a serious impact on system reliability. The Virtex-4 advanced packaging technology delivers superior signal integrity that reduces system design cycles and costs. High-performance FPGAs, without such packaging techniques, can result in multiple expensive board re-spins and time-consuming verification and debugging for high-speed applications. The signal integrity performance provided by Virtex-4 devices exceeds the performance provided by traditional design techniques such as soft/virtual grounds. Designers interested in learning more about this topic can view the latest BGA Crosstalk webcast by Dr. Howard Johnson (please see web site below).

Some of the key Virtex-4 technologies for superior signal integrity include:

• New SparseChevron™ package pin out
  
  o Highest ratio of VCCO/GND pin pairs to I/O pins for greater voltage stability
  
  o VCCO and GND pins adjacent to every SelectIO pin to minimize inductance
  
  
• Best on-chip decoupling capacitors
  
  
• Continuous Power/Ground planes

To further help designers understand the impact of FPGA package pinout on signal integrity, Xilinx is conducting a series a worldwide webcasts and on-demand demonstration videos showing both scaled FPGA package models and actual FPGAs.
