1.3. Design Flow

Use the IP Catalog and parameter editor to define and instantiate complex IP cores. Using the GUI ensures that you set all IP core ports and parameters properly.

If you are an expert user, and choose to configure the IP core directly through parameterized instantiation in your design, refer to the port and parameter details. The details of these ports and parameters are hidden in the parameter editor.
