Slots allow you to share the same graphic for identical parts of the =
chip, that's all. Thus, you don't need four different symbols for the =
four gates in a 7400. But you could represent a 7400 by separate symbols =
if you wanted: you are never required to use slots.
If the sections of the chip aren't identical, you'll generally want to =
use different graphics for each section, so slots are not the =
appropriate mechanism.
