I'm just looking for a bit of help getting started with Xilinx FPGAs. Specifically, I'm looking for the analogue to Altera's HEX and KEY keywords which are peripherals (HEX LED display and a toggle switch, respectively).

Can anyone provide a relevant link or resource that could get me going?

  • \$\begingroup\$ Hey is this the kind of thing that I'm looking for? xilinx.com/support/packagefiles/s6packages/6slx45csg324pkg.txt So if I reference "A4" in my verilog code that'll correspond to the IO pin right? \$\endgroup\$ – JDS Jan 8 '13 at 17:20

Based on your comment, I believe you are looking to assign pins. This is done in the Xilinx ucf (User Constraint File). See the constraints guide for more details.
