3. Parameter Settings
The Quartus II software provides the MegaWizard Plug-In Manager that helps you
quickly customize your megafunction variation. The parameter editor provides a list
of megafunctions and available options for each variation.
Altera recommends that you use the parameter editor to instantiate the ALTDLL and
ALTDQ_DQS megafunctions. However, for advanced users, if you want to bypass the
MegaWizard Plug-In Manager and use the megafunctions as directly parameterized
instantiations in your design, you can use the clear box generator. For more
information about the clear box generator, refer to
Appendix A, Clear Box Generator .
1 Some advanced parameters can only be modified through the clear box parameters.
ALTDLL Parameter Editor
This section provides information about the ALTDLL MegaWizard parameters.
1 For advanced users who may use the clearbox generator, the clearbox parameter
names are provided for the corresponding MegaWizard parameters.
The ALTDLL Parameter Settings page in the ALTDLL parameter editor allows you to
configure the parameters in the following pages:
■ General
■ DLL Offset Controls/Optional Ports
Table 3–1 shows the options available on the General page.
