I am using spartan 3 fpga board,I want to use its VGA port to display my output signals on the monitor,as far as i know you need a HDL code to program the port,if anyone can provide me verilog code,do i have to place it in my original verilog code which i have designed or download it seperately on the fpga
Thanks
Which FPGA board? The board manufacturer probably has example code you can download.
I'm guessing the VGA port is connected to the FPGA through an external DAC. In that case, you build one large project that does everything you want the FPGA to do, and download it into the chip.
It doesn't have to be HDL. It could be schematic entry or whatever other design tools you have available.
Sound like you have the Spartan-3 Starter Kit. That's a Digilent board. The "Board Verification" zip file contains VHDL examples. http://www.digilentinc.com/info/S3Board.cfm
