I bought a cheap-ish "Papilio Pro" FPGA board one day and wanted to do see if I could get it to output VGA directly (I did that with Atmel MCUs before for fun). So I installed Xilinx WebPack ISE and looked at various docs online. Other people's code (for example Mike Field's) was extremely helpful, too. I still feel I'd like to read a good book on Verilog design to close the gaps, if anyone is a pro I'm happy about recommendations.
