A Mux4 chip to implement Mux4Way16

[Jorge]

I figured it was much easier to implement Mux4Way16 if I designed a Mux chip that would select from 4 inputs. I called this one Mux4.

CHIP Mux4 {
     
    IN a, b, c, d, sel[2];
    OUT out;

    PARTS:
    // ...
}

[Spoiler Warning]

Mux4Way16 becomes a matter of calling Mux4 with each array item 16 times.

My implementation looks clean and clever to me, however if anyone could share their own thoughts on Mux4Way16 implementation would be great.

My initial implementation of Mux4Way16 was similar to yours but I eventually migrated to using Mux16s instead because the HDL is much easier to read with 3 parts than with 16.
