Does Mux 16 have 2 sets of 16 bit inputs or just 1 set?

Both a and b inputs are 16-bit buses.

From the Mux16.hdl file:
/**
 * 16-bit multiplexor. If sel=0 then out = a else out = b.
 */

CHIP Mux16 {

    IN  a[16], b[16], sel;
    OUT out[16];

    PARTS:
--Mark

This post was updated on .
how can sel be just 1 bit? if you have to choose between 16 inputs, it should be at least 8 bits. Also, why is out 16 bits wide? aren't we selecting 1 of 32 inputs?

The Mux16 chooses between two things: A and B.
A and B are 16 bits each.
