    I'm pretty much a n00b. Can you guys take a look at this and give me any feedback? I believe it works, I'm just not sure if there is an easier way. It's a up/down counter using D Flip Flops (those were required for the assignment).

    The assignment: "Design a 3-bit up/down counter using D flip-flops. It should include a control input called !Up/Down. If !Up/Down = 0, then the circuit should behave as an up-counter. If !Up/Down = 1, then the circuit should behave as a down-counter."

    Thanks!

    Oops, that version had a bug. This is the "new final" version, which I've tested more thoroughly. Comments/feedback are welcome, although I've already turned it in. :)
