With the new custom IP definition packaged and added to the IP catalog, you can validate that the IP works as expected when added to designs. To validate the IP, add a new customization of the UART IP to a project, and synthesize the design.
  1. From the Vivado IDE Getting Started page, select Manage IP > New IP Location to create a new project.

    Tip: You can use either an RTL project or a Manage IP project to validate IP.
  2. Click Next in the New IP Location dialog box.
  3. In the Manage IP Settings dialog box, set the following options as they appear in the following figure.
    Part

    Target language
    Verilog
    Target simulator
    Vivado simulator
    Simulator language
    Mixed
    IP location
    <Extract_Dir>/lab_1


  4. Click Finish to create the Manage IP project.

    A new Manage IP project opens in the Vivado IDE. The IP catalog opens automatically in a Manage IP project; however, the IP catalog does not contain the repository used to package the custom UART IP.

    You now add the IP repository to the IP catalog.

  5. In the IP Catalog window, right-click and select IP Settings, and expand IP to show Repository.
  6. In the Repository page, click the Add button to show and then select the IP Repositories dialog box.
  7. In the IP Repositories dialog box, browse to and select the following location:

    <Extract_Dir>/my_simple_uart.srcs/

  8. Click Select to add the selected repository, as shown in the following figure:

    The added location displays in the IP Repositories section, and any packaged IP found in the repositories displays under the IP in Selected Repository. The My Simple UART IP definition that you packaged in Step 3: Package the IP is listed.

  9. Click OK twice to add the IP repository to the IP Catalog and close the dialog box.
    Tip: To define a custom IP repository for use across multiple design projects, you can use the Tools > Settings command in the Vivado IDE to set the Default IP Repository Search Paths under the IP Defaults page. The default IP repository search path is stored in the vivado.xml file, and added to new projects using the IP_REPO_PATHS property for the current_fileset :set_property IP_REPO_PATHS {…} [current_fileset]. (See the Vivado Design Suite Properties Reference Guide (UG912) for more information.)
  10. In the search field at the top of the IP catalog, type UART.

    The My Simple UART is reported under the UserIP and Serial Interfaces categories that it was previously assigned to during packaging, as shown in the following figure.



    Note: This IP Catalog window shows when the Taxonomy and the Repository options are selected for grouping the IP. See the Vivado Design Suite User Guide: Creating and Packaging Custom IP (UG1118) for more information about IP Groups.
  11. Select the My Simple UART by clicking it under either the UserIP or Serial Interfaces category.
  12. Examine the Details pane of the IP Catalog window, as shown in the following figure.

    Notice that the details match the information provided when you packaged the IP.



  13. In the IP catalog, double-click My Simple UART to open the Customize IP dialog box, shown in the following figure.

  14. (Optional) In the Customize IP dialog box, click Documentation and open the Product Guide.
  15. Click OK, accepting the default Component Name and other options.

    The Vivado packager adds the customized IP to the current project, and displays the IP in the IP Sources window.

    The Generate Output Products dialog box opens, as shown in the following figure.



  16. Click Generate.

    This generates the various files required for this IP in the current Manage IP project, and launches an out-of-context (OOC) synthesis run for the IP, which creates a design checkpoint (DCP) file.

    Recall this OOC synthesis run uses the OOC XDC file that defines the necessary clocks for the standalone IP.

    The Generate Output Products dialog box re-opens to report the output products generated successfully.

  17. Click OK.
  18. Examine the IP Sources window and the various design and simulation source files that are added to the project.
  19. In the Design Runs window, shown in the following figure, verify that the Out-Of-Context synthesis run was successful.
