“The extra customization in these platforms improves the chip performance, shrinks the die size and therefore reduces cost because the silicon area is used more efficiently. Gartner Dataquest believes these domain-optimized platforms will accelerate the expansion of FPGAs into new markets.” - Serena Hsu, Analyst, Gartner Dataquest

“Virtex-4 changes the ASIC-FPGA decision process.  With its abundance of embedded cores, control processors, DSP, clock distribution, high-speed serial I/O, and memory, Virtex-4 domain-optimized platforms make FPGAs more efficient in terms of space, cost and power, while keeping the traditional advantages of time-to-market and flexibility. With mask costs rising, ASIC and ASSP development is more expensive, making FPGAs competitive for a broader range of applications.”
- Allan Armstrong, Program Director, Communications Semiconductors, RHK, Inc. 

"We have seen a continual improvement in our FPGA designs with the use of ISE 6 design tools from Xilinx. ISE 6 has not only shortened the time required for us to synthesize and implement our designs, but also makes very efficient use of internal device features, and allows for easy portability of projects between our various working groups."
- Antonio Borrego, FPGA Design Engineer StorageTek

"The Virtex II Pro was an excellent FPGA choice for our hardware implementation of the Just-In-Time optical (JIT) control plane protocol, due to the integrated MGTs and dedicated support of Xilinx field application engineers. With the introduction of the Virtex-4, MCNC-RDI will have the ability to increase processing speed and add additional features to the JIT protocol." 
- Dan Stevenson Vice President, Advanced Network Research MCNC-RDI 

“Xilinx provided us with the opportunity to participate in the Virtex-4 early access program. As a result, we are already benefiting from many of the features of these advanced Platform FPGAs in our next generation products. The Virtex-4's ChipSync technology made the design of high-speed parallel interfaces much easier, while achieving the desired performance. The programmable delay elements, SerDes feature, and regional clocking inherent to Virtex-4 devices offered critical features that previously were not available.”
- August Hidalgo, Senior Electrical Engineer, Agilent Labs

"The combination of Xilinx 6.3i, Virtex-4 and Design Compiler FPGA is an excellent choice for customers prototyping their complex standard cell ASIC designs in FPGAs. Devices such as Virtex-4 demand DC FPGA's superior timing quality of results, ability to deal with ASIC-like design complexity and tight links to Formality for formal verification. We have worked closely with Xilinx to develop this solution which is available to our customers today."
- Gal Hasson, Director of Marketing ASIC and FPGA Synthesis, Synopsys

"Closer cooperation between FPGA and EDA vendors becomes critical as high-density, high-speed programmable logic devices provide viable design alternatives to ASIC implementations. The Virtex-4 family, with its revolutionary ASMBL architecture, has the potential to expand the FPGA market into applications way beyond its traditional use in system prototyping and general logic. Mentor Graphics supports the new Xilinx devices and ISE 6.3 release with an advanced FPGA design tool suite that allows designers to take full advantage of these new reconfigurable platforms."
- Simon Bloch, General Manager Design Creation and Synthesis Division, Mentor Graphics

"We are very excited about the capability of the new Virtex-4 FPGA family. The combination of high capacity, performance and potential for lower system cost allows our customers to use FPGAs in a much broader range of applications than ever before. We have been working with Xilinx for over a year to integrate our best-in-class synthesis support for this new family into the 6.3i version of the Xilinx Integrated Software Environment."
- Jeff Garrison, Director FPGA Marketing, Synplicity

"The role of FPGAs will continue to grow, especially as custom ASICs become more difficult to justify due to higher up-front engineering costs. We believe next generation solutions such as Virtex-4 will be at the forefront of this migration as more functional-specific FPGAs are created to address certain application markets for longer product life cycles than in the past where ASICs were traditionally the logical next step due to ramping volumes. 
- Sean Lavey, Program Manager, IDC Market Research

"Leveraging the proven success of the Xilinx Virtex series and the company's one-year lead in 90nm process technology, the Virtex-4 family is poised to dramatically alter the technical and business dynamics of the traditional programmable logic market. The combination of the enhancements brought on by the new Virtex-4 FPGAs and the benefits of a multi-platform approach will accelerate the shift to FPGAs over ASICs and ASSPs." 
- Bob Merritt, Analyst, Semico Research

"The Xilinx ASMBL architecture is novel in that it enables a choice of platforms with an optimized feature mix. This is a compelling product differentiation, especially for DSP designers looking to use an FPGA as an accelerator for their DSP processor in very high performance applications." 
- Will Strauss, president of Forward Concepts

"The new Virtex-4 FPGA family, along with its underlying ASMBL architecture, represent a technology breakthrough that shifts the cost models and role of FPGAs in systems design," said  "For the first time, designers can choose an FPGA platform with the right mix of capabilities for their specific design." 
- Gerald S. (Jerry) Worchel Principal Analyst, Digital Engines Service, In-Stat/MDR

"This enhanced platform approach incorporates advanced system features that are particularly useful in a wide-range of embedded applications that require high-performance processing and high-bandwidth I/O. Particularly for applications that are dominated by control flow operations involving complex data types, the Virtex-4 FX full-featured platform is an ideal solution. "
