2024.1 English

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:

  1. 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.
  2. Click OK.
