Xilinx free development system supports Linux http://www.eetimes.com/news/design/showArticle.jhtml;jsessionid=MJ2FPNHFUVMZ2QSNDBESKHA?articleID=159908000 "While this is the first time Xilinx has included Linux support on a downloadable Webpack release, other Xilinx products have supported Linux over the past few years. Xilinx's ISE 7.1i, released March 1, supports 64-bit Linux. In addition to Linux support, the Webpack 7.1i includes support for Xilinx's Spartan-3 Generation, Virtex-4 and CoolRunner-II families. Webpack 7.1i also includes a technology viewer that provides a schematic view of post-synthesis netlists, a design summary view that updates as new information becomes available and messaging filtering capabilities for report customization. Webpack 7.1i also includes cable server features that enable remote configuration of devices across a network. WebPack 7.1i is available for download from Xilinx's Web site.
