Xilinx Solves Memory Interface Design Challenges With Virtex-4 Memory Development System

Easiest-to-use memory solution with unique ChipSync source synchronous circuitry cuts design time and provides industry's highest bandwidth

SAN JOSE, Calif.
Nov 9, 2004

Xilinx Inc. (NASDAQ: XLNX) today announced the immediate availability of its ML461 Virtex-4 memory development system, the most flexible and highest bandwidth memory interface solution in the industry. Enabled by the innovative Virtex-4 ChipSync™ source synchronous technology, an automated, intelligent adjustment feature, the solution drastically reduces design time. The Xilinx® ML461 development system includes proven reference designs, an easy-to-use Memory Interface Generator tool, and a complete hardware platform to provide designers with the ultimate design flexibility. Xilinx will showcase its new development system November 9-10 at the Denali Memcon Conference, Santa Clara Convention Center, Santa Clara, California.

With the ML461 Virtex-4 memory development system, customers can now achieve more than twice the bandwidth of any other programmable solution using the latest memory technology available, including 533Mbps DDR2 SDRAM and 300MHz QDR II SRAM, with bus widths up to 144 bits.

The Virtex-4 ChipSync technology, implemented in every I/O, simplifies the implementation of memory interfaces by compensating for routing, process, temperature, and voltage variations that produce skew between data and clock signals. This unique feature alleviates post-design adjustments and significantly improves customer design cycle and system reliability. The Xilinx memory solutions are verified in hardware using the latest and highest speed grade memory devices from industry leaders like Samsung and Micron.

"Xilinx Virtex-4 FPGAs provide high bandwidth programmable interface solutions for our industry-leading QDR II SRAM, DDR2 and DDR SDRAM memory devices," said I. J. Lee, associate director of SRAM and MCP Product Marketing at Samsung Semiconductor, a global leader in semiconductor technology. "With the combination of Xilinx fully hardware-verified, high performance Virtex-4 solutions and our memory devices, customers achieve greater design flexibility and cost savings while reducing time-to-market."

"The Virtex-4 memory interface enables system designers to implement a flexible, high bandwidth memory system resulting in robust and very competitive end products," said Mike Black, product marketing manager at Micron, one of the world's leading providers of advanced semiconductor solutions. "As a leading supplier of high-performance memory technologies, such as DDR2 and RLDRAM® II, Micron is excited to see the Xilinx Virtex-4 memory interface solutions enter the market."

The Virtex-4 ML461 system includes hardware proven reference designs, a Memory Interface Generator tool and complete hardware platform. The Reference Designs provide high design margins to maximize system performance and reliability by leveraging advanced Virtex-4 features such as ChipSync, SmartRAM, and Xesium differential clocking. The designs, available in Verilog and VHDL, use a modular approach to provide distinct physical layer and controller blocks, enabling easy migration to other memory devices.

The Memory Interface Generator, a user-friendly software tool, supports any device/package combination -- providing additional flexibility for system designers looking to easily customize the reference designs. The hardware platform features four Xilinx Virtex-4 LX25 devices and interfaces to DDR2, DDR SDRAM, QDR II SRAM, RLDRAM II, and FCRAM II memory devices. Also included are schematics and gerber files.
