help about fpga?
 

i am learning fpga. but i dont know how i can programmable any fpga. i think i will work pruduct of xilinx.

Not sure what you need, but Xilinx Design Tools and boards could be a start. Xilinx states that ISE works with Win and RHLE, though it apparently run ok in Slack 12 through Wine (didn't tried to run the RHLE in Slack).
Or try Altera at http://www.altera.com/products/software/sfw-index.jsp

There are boards and kits with the HW built and ready for testing and programming.

At OpenCores you find many user built cores for common needs, or take a look at the VHDL-Cookbook.pdf.

thanks friend vhdl book is very good. i looked for like this book.is there more docs about xilinx?
