adder + mux

[David Grohmann]

are we allowing speed increases by feeding the mux selector an input
sooner than the rest of the circuit so we dont have to count the time of
the mux in the total time?

[Geoffrey Fairchild]

I believe we always have to include the mux time in the total time. He
showed us how you can make those optimizations in the real world, but he
said that to make things simpler for Behnam to grade, we're going to always
factor in the mux speed.

Geoffrey is correct.

David's solution, although factually more accurate in many cases, could
involve other circuit issues beyond the scope of this class. I decided
that you should always just add the mux time to simplify the analysis and
enforce homogeneity of solutions.
