I would rather appreciate if anyone give me some advice to use generate or others to describe it.

Here's a mux. Wrap your head around the logic, and you can figure out how to describe a demux :)

The comments in the code described it fairly well. The PDF is a figure to help describe the indexing.

Cheers,
