You don't have to get into analog problems to require 'the right
approach'. I've seen boards built to 150 Mhz without board trace
delay or reflection requiring analog analyis.

'Just ones and zeroes' can be more than enough of a barrier. Just try
to design anything with more than a few states. There are issues of
state machine minimization, race and hazard detection and elimination,
and verification which have nothing to do with analog signals, per se.

Good teaching is good teaching, and every subject benefits from such.
