Traversing the Design Hierarchy and Creating a Design Configuration View

The Cadence® hierarchy editor creates a configuration view that provides expansion information controlling how the design hierarchy can be traversed.

Configuration views

In the above example, the library designLib contains two configuration definitions with the view names mixedConfig and logicConfig. You can use the hierarchy editor to open these views.

About the Hierarchy Editor

The hierarchy editor is a tool you use to create and edit a configuration. A configuration is a set of rules that defines which cellviews under a top-level cell are to be considered part of the design for netlisting, simulation, design partitioning for mixed signal simulation, and analysis.

The hierarchy editor lets you view the hierarchy of a design using a table or a tree format to manage multiple components and views.

You use the hierarchy editor to do the following:

■Change the global bindings

■Add cell-based bindings and cell-based view lists

■Add instance-based bindings and instance-based view lists

■Update your configuration to see the effect of your work

■Change instance bindings inside a block

■Save your rules
