This chapter gives an example of how to parameterize a CIC MegaCore function.
The Parameter Settings page provides the same options whether the MegaWizard
interface has been opened from the DSP Builder or MegaWizard Plug-In Manager
flow. However, the EDA and Summary tabs are not visible when you are using the
DSP Builder flow.
For information about opening the MegaWizard interface, refer to the
on page
The MegaWizard interface only allows you to select legal combinations of parameters,
and warns you of any invalid configurations.
To parameterize your CIC MegaCore function, follow these steps:
1. Specify your required values in the Parameter Settings: Architecture page. For
Table 3–1. Example Parameters for the CIC MegaCore Function Architecture Tab
Parameter
Filter type
Number of stages
Differential delay
Rate change factor
Enable variable rate change factor
Number of interfaces

For more information about these parameters, refer to
2–1.
If you enable the variable rate change factor option you can also specify
minimum and maximum values instead of specifying an actual rate change
factor. The data storage options are only available when the number of
channels per interface is greater than 4.
