How You Can Use External Classes
To use an external object in OpenROAD, you must first register the library that contains the external objects by using the External Class Library Editor.
Next, you have the option of doing either or both of the following:
• Adding external objects to an OpenROAD frame using the Frame Editor
• Declaring variables that reference external classes
For more information about these procedures and facilities, see the Workbench User Guide.
When you register an external class library, be aware that one library can have more than one external class. For example, registering a single external class library might provide three external classes that can be used in an OpenROAD application.
