Altera Integer Arithmetic IP - Manual (Page 7)

Altera also provides floating-point IP cores. For more information about the floating-point IP cores, refer
to the Floating-Point IP Cores User Guide .
Design Example Files
Altera provides design example files that are simulated in the ModelSim ® -Altera software to generate a
waveform display of the device behavior.
You should be familiar with the ModelSim-Altera software before using the design examples. To get
started with the ModelSim-Altera software, refer to the ModelSim-Altera Software Support page on the
Altera website. The support page includes links to such topics as installation, usage, and troubleshooting.
For more details about the design example for a specific IP core, refer to the “Design Example” section for
that megafunction.
Design examples are provided only for some IP cores in this user guide.
Installing and Licensing IP Cores
The Altera IP Library provides many useful IP core functions for production use without purchasing an
additional license. You can evaluate any Altera ® IP core in simulation and compilation in the Quartus ® II
software using the OpenCore ® evaluation feature. Some Altera IP cores, such as MegaCore ® functions,
require that you purchase a separate license for production use. You can use the OpenCore Plus feature to
evaluate IP that requires purchase of an additional license until you are satisfied with the functionality and
performance. After you purchase a license, visit the Self Service Licensing Center to obtain a license
number for any Altera product.
