FPGA replaces large capacity ASICs

Xilinx Inc. offers Virtex-7 2000T FPGA that offers equipment manufacturers with an integration platform to help them overcome the challenges of lowering power while increasing performance and capabilities.

The Virtex-7 2000T FPGA is touted as the industry's highest-capacity programmable logic device (PLD) built using 680 crore transistors. It offers customers access to 20 lakh logic cells, equivalent to 2 crore ASIC gates, for system integration, ASIC replacement, and ASIC prototyping and emulation.

This capacity is made possible by Xilinx's stacked silicon interconnect technology. It is the first application of 2.5D IC stacking that yields twice the capacity of competing devices and leaping ahead of what Moore's Law could offer in a monolithic 28nm FPGA, noted Xilinx. Customers are using Xilinx's Virtex-7 2000T FPGA to replace large capacity ASICs to achieve overall comparable total costs in a third of the time. It can also create integrated systems that increase system bandwidth and reduce power by eliminating I/O interconnect, and accelerate the prototyping and emulation of advanced ASIC systems.

Virtex-7 2000T offers access to 20 lakh crore logic cells, equal to 2 crore ASIC gates.

By eliminating the I/O interfaces between different ICs on a circuit board, a system's overall power consumption can be reduced considerably. Customers can also lower BOM, test and development cycle costs when fewer IC devices are required on a circuit board. Because the ICs align side by side on a silicon interposer, the technology avoids the power and reliability issues that can result from stacking multiple dies on top of each other. The interposer includes more than 10,000 high speed interconnects between each die enabling the high-performance integration required for a wide range of applications.

The FPGA claims to give customers the capacity, performance and power typically only found in large capacity ASICs, with the added benefits of re-programmability, said the company. For the growing number of systems and markets where economics work against ASIC development, the Virtex-7 2000T FPGA offers a unique, scalable alternative to the risk of re-spins and more than Rs.224.22 crore ($50 million) in non-reoccurring engineering (NRE) costs of a 28nm custom-made IC, added Xilinx.

Virtex-7 2000T FPGA initial engineering samples are shipping now. Customers can start designing today to take advantage of the price, performance and low power consumption advantages offered by the 7 series FPGAs.
