FPGA Simple XOR Tutorial
From George Smart's Wiki
When I was starting out, I really wanted something like this. Then Anthony Burch started his excellent videos on the basics of FPGA design and that got me going. When trying to go over one of his videos, I noticed that so much had chanced, and since I'd forgotten so much, I decided that once I'd figured it out, I'd add a simple XOR project in Verilog. The project starts from me opening the Xilinx ISE 12.1, and finishes with me testing it on the Spartan-3E board (it works, of course!). I just thought I may help some of you. It's in HD, so switch youtube to 1080p so you can read the text. I apologise for my voice (I'm not a natural speaker) and for the fact that I was kind of making it up as I went along. But I'm sure it may help.
