Introduction

The Virtex™ -E Extended Memory (Virtex-EM) family of FPGAs is an extension of the highly successful Virtex-E family architecture. The Virtex-EM family (devices shown in Table 1) includes all of the features of Virtex-E, plus additional block RAM, useful for applications such as network switches and high-performance video graphic systems.

Xilinx developed the Virtex-EM product family to enable customers to design systems requiring high memory bandwidth, such as 160 Gb/s network switches. Unlike traditional ASIC devices, this family also supports fast time-to-market delivery, because the development engineering is already completed. Just complete the design and program the device. There is no NRE, no silicon production cycles, and no

additional delays for design re-work. In addition, designers can update the design over a network at any time, providing product upgrades or updates to customers even sooner.

The Virtex-EM family is the result of more than fifteen years of FPGA design experience. Xilinx has a history of supporting customer applications by providing the highest level of logic, RAM, and features available in the industry. The Vir- tex-EM family, first FPGAs to deploy copper interconnect, offers the performance and high memory bandwidth for advanced system integration without the initial investment, long development cycles, and inventory risk expected in traditional ASIC development.

Virtex-E Compared to Virtex Devices

The Virtex-E family offers up to 43,200 logic cells in devices up to 30% faster than the Virtex family.

I/O performance is increased to 622 Mb/s using Source Synchronous data transmission architectures and synchronous system performance up to 240 MHz using sin- gled-ended SelectI/O technology. Additional I/O standards are supported, notably LVPECL, LVDS, and BLVDS, which use two pins per signal. Almost all signal pins can be used for these new standards.

Virtex-E devices have up to 640 Kb of faster (250MHz) block SelectRAM, but the individual RAMs are the same size and structure as in the Virtex family. They also have eight DLLs instead of the four in Virtex devices. Each individual DLL is slightly improved with easier clock mirroring and 4x frequency multiplication.

VCCINT, the supply voltage for the internal logic and memory, is 1.8 V, instead of 2.5 V for Virtex devices. Advanced

processing and 0.18 mm design rules have resulted in smaller dice, faster speed, and lower power consumption.

I/O pins are 3 V tolerant, and can be 5 V tolerant with an external 100 W resistor. PCI 5 V is not supported. With the addition of appropriate external resistors, any pin can tolerate any voltage desired.

Banking rules are different. With Virtex devices, all input

buffers are powered by VCCINT. With Virtex-E devices, the LVTTL, LVCMOS2, and PCI input buffers are powered by

the I/O supply voltage VCCO.

The Virtex-E family is not bitstream-compatible with the Virtex family, but Virtex designs can be compiled into equivalent Virtex-E devices.

The same device in the same package for the Virtex-E and Virtex families are pin-compatible with some minor exceptions. See the data sheet pinout section for details.

General Description

The Virtex-E FPGA family delivers high-performance, high-capacity programmable logic solutions. Dramatic increases in silicon efficiency result from optimizing the new architecture for place-and-route efficiency and exploiting an aggressive 6-layer metal 0.18 mm CMOS process. These advances make Virtex-E FPGAs powerful and flexible alter-

natives to mask-programmed gate arrays. The Virtex-E family includes the nine members in Table 1.

Building on experience gained from Virtex FPGAs, the Vir- tex-E family is an evolutionary step forward in programmable logic design. Combining a wide variety of programmable system features, a rich hierarchy of fast, flexible interconnect resources, and advanced process technology, the Vir- tex-E family delivers a high-speed and high-capacity programmable logic solution that enhances design flexibility while reducing time-to-market.

Virtex-E Architecture

Virtex-E devices feature a flexible, regular architecture that comprises an array of configurable logic blocks (CLBs) surrounded by programmable input/output blocks (IOBs), all interconnected by a rich hierarchy of fast, versatile routing resources. The abundance of routing resources permits the Virtex-E family to accommodate even the largest and most complex designs.

Virtex-E FPGAs are SRAM-based, and are customized by loading configuration data into internal memory cells. Configuration data can be read from an external SPROM (master serial mode), or can be written into the FPGA (SelectMAP™ , slave serial, and JTAG modes).

The standard Xilinx Foundation Series™ and Alliance Series™ Development systems deliver complete design support for Virtex-E, covering every aspect from behavioral and schematic entry, through simulation, automatic design translation and implementation, to the creation and downloading of a configuration bit stream.

Higher Performance

Virtex-E devices provide better performance than previous generations of FPGAs. Designs can achieve synchronous system clock rates up to 240 MHz including I/O or 622 Mb/s using Source Synchronous data transmission architechtures. Virtex-E I/Os comply fully with 3.3 V PCI specifications, and interfaces can be implemented that operate at 33 MHz or 66 MHz.

While performance is design-dependent, many designs operate internally at speeds in excess of 133 MHz and can achieve over 311 MHz. Table 2, page 3, shows performance data for representative circuits, using worst-case timing parameters.
