This will be the Xilinx webpack thing I keep hearing about...

I like PA Oscs, nice, stable, sexy...

I agree,
I just wish there was a decent book or Webpage with an 'idiots guide to FPGA
and VHDL'
something simple and step by step...

I have some VHDL code written by a friend and some of it makes sense, and
some of it just looks like russian to me..

Anyone up for doing this?
Im sure that a step by step FPGA tutorial section would be a huge hit
amongst diy'ers.
