The ports and interfaces are determined during the Create and Package New IP wizard by parsing the top-level HDL file. When you want to change ports due to a change to the HDL source after packaging, you can re-import the ports.
Important: When you re-import the top-level source file, all pre-existing HDL parameters and associated data are removed.
To import ports:
- From the Ports and Interfaces page,
right-click and select Import IP Ports. In
the Import Ports from HDL dialog box,
and provide the following information:
- Top-Level source file
- The top-level source HDL file that contains the top-level entity or module of the custom IP.
- Top entity name
- The name of the top-level entity or module that contains the ports of your custom IP.
- Click OK.
