VERILOG problem

Hello everyone,
Does anyone know how to do this problem? I have to do it in VERILOG.

Design a windshield wiper with the following operation:
- a user can control the wiper on three positions
- position1: the wiper is off
- position2: the wiper wipes every twenty time units
- position3: the wiper wipes every other time unit


submit the design and stimulus code, and not more than three pages of results (waveforms or other).

Please help me in getting the solution. I am unable to do it.
Thanks,
Sai.

Re: VERILOG problem

Sounds like easy homework to me. You may want to review your course reading material.

You will want a module that has position[1:0] as the input and wipe as the output. You will also want to have a clock as an input to use as your "time unit"

Position 1: Hopefully you can figure that one out

Position 2: Can you count to 20, then wipe?

Position 3: Wipe every other clock

For your stimulus generate clock cycles, set the postion, get the output, set the next position, etc.
