The Product block supports two scalar inputs (no multidimensional Simulink
signals). Operand a is multiplied by operand b and the result output on r as the
following equation shows:

The Simulink software also provides a Product block. If you use the Simulink
Product block in your model, you can use it only for simulation.

The Product block supports clock phase selection while the Multiplier block
does not.
The Product block uses implicit input port data widths that are inherited from
the signals’ sources, whereas the Multiplier block uses explicit input port data
widths that you must specify as parameters.
The Product block allows you to use the LPM multiplier megafunction, whereas
the Multiplier block always uses the LPM.
