The Virtex-4TM Family is the newest generation FPGA from Xilinx. The innovative Advanced Silicon Modular Block or ASMBLTM column-based architecture is unique in the programmable logic industry. Virtex-4 FPGAs contain three families (platforms): LX, FX, and SX. Choice and feature combinations are offered for all complex applications. A wide array of hard-IP core blocks complete the system solution. These cores include the PowerPCTM processors (with a new APU interface), Tri-Mode Ethernet MACs, 622 Mb/s to 11.1 Gb/s serial transceivers, voltage/temperature system monitor blocks, dedicated DSP slices, high-speed clock management circuitry, and source-synchronous interface blocks. The basic Virtex-4 building blocks are an enhancement of those found in the popular Virtex-based product families: Virtex, Virtex-E, Virtex-II, Virtex-II Pro, and Virtex-II Pro X, allowing upward compatibility of existing designs. Virtex-4 devices are produced on a state-of-the-art 90-nm copper process, using 300 mm (12 inch) wafer technology. Combining a wide variety of flexible features, the Virtex-4 family enhances programmable logic design capabilities and is a powerful alternative to ASIC technology.
