I'm pretty sure that's the point of the class..

Learning verilog. And figuring out how to talk to the hardware..

I haven't looked at the DE1 lately, but there should be a codec between the FPGA and line-out. First dig up the datasheet for that part, and figure out how to send data to it.. (Most likely an I2S interface)

Then write the verilog code to send some 1-KHz to 5 KHz tone tone to the CODEC, for Line-out.

If you can make it make a tone, you can then work on the alarm clock portion.
