HDL files created outside of UML2HDL can be instantiated on UML Object Diagrams as UML Objects.
The HDL Palette shows a list of HDL files that have been imported into UML2HDL.
To import a previously created HDL module:
| 1. | select Import from the File menu; | 
| 2. | select Import HDL Module from the Import submenu; | 
| 3. | using Open dialog specify the path to an HDL file you'd like to import and click Ok. | 
OR
| 1. | select Open HDL Module from the File menu; | 
| 2. | using Open dialog specify the path to an HDL file you'd like to open and click Ok. | 
To instantiate one of these HDL files as an object on a UML Object Diagram, drag and drop one of the entries from the HDL Palette to the UML Diagram panel.
| 
 | The summary for each HDL file can be displayed as a hint by pausing the mouse cursor over any particular entry on HDL tab. |
