Structural and Behavioral descriptions
Structural — Pretty much working at the gate level. Organizing
various types of basic logic elements and describing how they are
connected. If you want to add two twelve bit signals you have to
design and build the adder.
Behavioral — Pretty much saying what you want. Not so much
concerned with how it is accomplished. For example specifying
that two twelve bit signal values be added together without
specifying how this is to be physically accomplished.
