Some embodiments provide a system that facilitates the creation of a design in an electronic design automation (EDA) application. During operation, the system obtains a set of parameters associated with parameterized connections in a hierarchy of the design and a set of net assignments to the parameters. Next, the system displays the parameters and the net assignments to a user of the EDA application through a graphical user interface (GUI) associated with the EDA application. Finally, the system enables modifications to the net assignments by the user through the GUI.
