3.3. Creating IP Components in the Component Editor

The Platform Designer Component Editor allows you to create and package an IP component and parameterization GUI. When you use the Component Editor to define a component, Platform Designer writes the information to an _hw.tcl file.
Figure 133. Component Editor

The Platform Designer Component Editor allows you to perform the following tasks:

  • Specify component’s identifying information, such as name, version, author, etc.
  • Specify the SystemVerilog, Verilog HDL, VHDL files, and constraint files that define the component for synthesis and simulation.
  • Create an HDL template to define a component's interfaces, signals, and parameters.
  • Set parameters on interfaces and signals that can alter the component's structure or functionality.

If you do not have a top-level HDL component file, you can use the Platform Designer Component Editor to add interfaces, signals, and parameters. In the Component Editor, the order in which the tabs appear reflects the recommended design flow for component development. You can use the Prev and Next buttons to guide you through the tabs.

In a Platform Designer system, the interfaces of a component are connected in the system, or exported as top-level signals from the system.

If the component is not based on an existing HDL file, enter the parameters, signals, and interfaces first, and then return to the Files tab to create the top-level HDL file template. When you click Finish, Platform Designer creates the component _hw.tcl file with the details that you enter in the Component Editor.

When you save the component, it appears in the IP Catalog.

If you require custom features that the Platform Designer Component Editor does not support, for example, an elaboration callback, use the Component Editor to create the _hw.tcl file, and then manually edit the file to complete the component definition.
Note: If you add custom coding to a component, do not open the component file in the Platform Designer Component Editor. The Platform Designer Component Editor overwrites your custom edits.
