Altera provides two distinct methods for implementing various modes of the DSP
block in a design: instantiation and inference. Both methods use the following
Quartus II megafunctions:

You can instantiate the megafunctions in the Quartus II software to use the DSP block.
Alternatively, with inference, you can create an HDL design and synthesize it with a
third-party synthesis tool (such as LeonardoSpectrum, Synplify, or Quartus II Native
Synthesis) that infers the appropriate megafunction by recognizing multipliers,
multiplier adders, multiplier accumulators, and shift functions. With either method,
the Quartus II software maps the functionality to the DSP blocks during compilation.
For instructions about using the megafunctions and the MegaWizard Plug-In
Manager, refer to the Quartus II Software Help.

Handbook.
