U SING A LTERA M EGAFUNCTIONS
When the OpenCore Plus hardware feature is turned on in the More
Compilation Process Settings dialog box, the Quartus II software
inserts a small amount of control logic in your design. This logic can
have an adverse effect on fitting, especially with small devices. You can
turn off the OpenCore Plus hardware evaluation feature to direct the
Quartus II software to omit the additional logic.
Using the MegaWizard Plug-In
Manager
The MegaWizard Plug-In Manager helps you create or modify design files
that contain custom megafunction variations, which you can then instantiate
in a design file. These custom megafunction variations are based on
Altera-provided megafunctions, including LPM, MegaCore, and AMPP
functions. The MegaWizard Plug-In Manager runs a wizard that helps you
easily specify options for the custom megafunction variations. The wizard
allows you to set values for parameters and optional ports. You can open the
MegaWizard Plug-In Manager on the Tools menu or from within a Block
Design File, or you can run it as a stand-alone utility.
Instantiating Megafunctions in the
Quartus II Software
You can instantiate Altera megafunctions and LPM functions in the
Quartus II software through direct instantiation in the Block Editor, through
instantiation in HDL code (either by instantiating through the port and
parameter definition or by using the MegaWizard Plug-In Manager to
parameterize the megafunction and create a wrapper file), or through
inference.
Altera recommends that you use the MegaWizard Plug-In Manager to
instantiate megafunctions and create custom megafunction variations. The
wizard provides a GUI for customizing and parameterizing megafunctions,
and ensures that you set all megafunction parameters correctly.
