One of the chapters in "The Art & Science of Analog Circuit Design" describes
how, for a mercury delay line memory, the "hook up the blocks" approach was
unable to provide a working design; designing all the blocks "in paralle"
allowed for a very inexpensive solution.

The vast majority of engineers out there are of the "hook up the blocks"
variety; it is much easier than designing the blocks themselves!
