Traversing the Design Hierarchy and Creating a Design Configuration View

Displaying the Current Hierarchical Scope

When you display the hierarchical scope of your design, you can

■View all the instance names and corresponding cell names of the current window

■View a list of the instance names you have descended into and in which cell name and view name they are located

To display the current hierarchical scope, do the following:

1.Choose Design – Hierarchy – Show Scope.

A dialog box appears that lists the instance names and the corresponding cell names of the current window.

2. Click Close to close the dialog box.

About the Hierarchy Editor within the Schematic Composer

The hierarchy editor integration with the Virtuoso® schematic composer provides a convenient way to synchronize the configuration database with the Cadence design framework II (DFII) database. From the Hierarchy-Editor menu on the schematic composer window, you can open the hierarchy editor, synchronize the database, set instance binding, and view the current set of view binding information.

The following products use the hierarchy editor within the schematic composer: mixed-signal circuit design environment, analog circuit design environment, Verilog® -XL simulator, and VHDL integration.

The Hierarchy-Editor menu provides four commands:

■Edit Configuration

■Update

■Set Instance Binding

■Show Views Found

Working with a Design Configuration within the Schematic Composer
