FPGA performance reaches new heights with the Stratix™ II device family-the industry's fastest and highest-density FPGAs. Built on a new and innovative logic structure, Stratix II devices on average deliver 50% faster performance and offer more than twice the logic capacity of first-generation Stratix FPGAs. Stratix II devices extend the possibilities of FPGA design,

Stratix II devices were designed in concert with the Quartus® II software to deliver unmatched performance and ease-of-use. The Quartus II software is the industry's most advanced development software for high-density FPGAs and provides a comprehensive suite of synthesis, optimization, and verification tools in a single, unified design environment.

With support for migration to HardCopy™ structured ASICs, Stratix II FPGAs offer the industry's only seamless development path from FPGA prototype to high-volume, structured ASIC production. Designing with HardCopy devices allows you to reduce development costs and still get the flexibility and time-to-market advantages associated with FPGAs.

Best-in-Class Features

Stratix II devices improve on the features that set new standards in FPGAs (Figure 1). New device capabilities such as the new logic structure and design security technology round out the industry's most advanced FPGA feature set.
