Opening a Hierarchy Editor Menu within the Schematic Composer

To open the hierarchy editor menu within the schematic composer, do the following:

Choose Tools – Hierarchy Editor.

The Hierarchy-Editor menu appears in the schematic composer menu banner.

Editing a Design Configuration within the Schematic Composer

To edit the configuration when the hierarchy editor is not present, do the following:

1.Open the design configuration.

If the Hierarchy-Editor menu is not visible on the menu banner, you need to install it.

2.Choose Hierarchy-Editor – Edit Configuration.

The hierarchy editor appears with information pertaining to your configured schematic.

For more details about using the hierarchy editor, refer to the Hierarchy Editor User Guide.

Setting Instance Bindings

The Set Instance Binding command lets you define the view to use and lets you choose the inherited view list. You can also set the view to use and the inherited view list from the hierarchy editor, but the Set Instance Binding command from the schematic composer gives you more flexibility on the scope of changes.

To define the view to use and to choose the inherited view list, do the following:

1.Choose Hierarchy-Editor – Set Instance Binding.

You are prompted to open the Hierarchy Editor form if it is not already open.

Traversing the Design Hierarchy and Creating a Design Configuration View

The Set Instance Binding form appears.

2.Select one or more instances in the design that you want changed.

The current instance is highlighted and its name is displayed in the Instance Name field.

3.Change the Apply To cyclic field to displaycurrent instance (the main selection), all selected instances (in a group selection, including the main selection), or all instances (in the cellview).

If you choose all selected or all instances, another cyclic field appears on the form.

Choose same master or any master.

4.Select View To Use to be bound to these instances.

Views common to all of the selected instances are available for selection. If you want to revert to the default bindings for your configuration in the hierarchy editor, set theView

To Use field to<Default>.

5.To keep the inherited view list as is and not build a new inherited view list (default), turn on the As Is field.

You can change the inherited view list. To build a new inherited view list, refer to the following section.

6.Click Apply to make your changes.

Your changes are reflected in theView To Use field in the hierarchy editor for the instances you selected.

7.To propagate your changes to subordinate instances and save your changes, choose

Hierarchy-Editor – Update in the schematic window.

All instances that are affected by your View To Use selection are changed in the hierarchy editor and saved.

Updating a Design Configuration

After you edit the configuration, such as defining a new instance binding, you need to update the information in the hierarchy editor. To update a configuration from the schematic composer, do the following:

Choose Hierarchy-Editor – Update.

If you are using the schematic composer to edit cellviews, you must save them in order to have the edits you made reflected in your configuration.

The hierarchy editor is updated with the following information:

■The cellviews you selected are saved

■Your hierarchy editor display is updated

■The schematic composer is updated with the new configuration

Building a New Inherited View List

After choosing Hierarchy-Editor – Set Instance Binding and completing the steps in the previous section, do the following:

1.Turn the As Is button off in the Inherited View List field.

2.Type in the inherited view list or click Build to construct the view list.
