FWIW, I didn't look at anything from Xilinx directly in my code; I just looked at Simon's code, Timothy's framework, and the other stuff mentioned in my files (I don't remember if I used any sources for the head0_module.v file, but they would be mentioned. I have links to all the sites I used in vidsim.v). I don't know if this makes my code any "cleaner" than Simon's code, but if it helps... If you want to generate timing numbers, you can use "gtf 800 600 60" which actually gives slightly different values than the Xilinx numbers and is based off a 38.22 Mhz clock (which explains the number changes). Hope that helps! _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
