First, there is no "correct" approach. If your chip passes the test, it's good.

You can write more concise implementations by using higher-level abstractions. Think about how you can use 3 DMux chips to make a DMux4Way. You want the data path to look something like this:

          in
          |
          *
         / \
        /   \
       /     \
      *       *
     / \     / \
    |   |   |   |
    a   b   c   d

The trick is what you do with the Muxs' sel inputs to get the data where it needs to go.
