"Hello World" project for an FPGA (on a Spartan3 board)

Flash an LED at a rate of roughly once per second. This makes sure that:

Once you get that done, try each of the peripherals in as simple of way as you can.

Blink the LEDs. That needs a counter or such to slow it down enough to see. If you have a scope, you can bypass that compliction.

There are a handful of designs that you can download from the Spartan-3 Starter Kit web page.

For a real simple HDL Hello world equivalent I would recommend 'Digital Clock using Multiplexed 7-Segment Display'

Cheers, Shal> I just got my Spartan3 board from Digilent, and I noticed it didn't come

A 2-input AND gate would be a good one. Make 2 of the switches on your board as the inputs. Connect the output to one of the LED.

There should already be Digilent's test program loaded onto the board. On the pegasus board (S2) it increments the 7 segment display and connects each of the switches to the LED's. Plug it in and try it out. Digilent's website also has instructional videos for using Xilinx Webpak.

I would start by modifying Digilent's program. Then perhaps make a switch debouncer and make the led flash. Then perhaps play with the seven segment display - like an incrementer that increments the display each time a button is pushed.

I would save the digital clock for later unless you have prior HDL experience. A digital clock is alot to do before testing at least once.
