Grouping Instances

Grouping instances allows you to select two or more instances in a module and put them in a new child module.

1.Hold down the Shift key and click left mouse button to select two or more instances.

2.Click left mouse button on Group Instances icon on the schematic tool bar.

3.Enter a name for the new module in the Enter Module Name box.

Click Ok.

The selected instances are now grouped into a new module. In the current view the selected instances are replaced by one instance. The new module created from grouping the instances is added to the design and displayed in the module hierarchy in the module browser as a child of the currently displayed module.

Creating a Unique Module

Uniquifying instances removes the dependency on an existing module and ties the instances to a newly created module based on the original.

1.Hold down the Shift key and click left mouse button to select two or more instances.

2.Click left mouse button on Uniquify Instances icon on the schematic tool bar.

To uniquify a module you must select one or more instances in that module. The command only works on the instances in the displayed module. Other instances of the module may exist at other levels of the design, but you must go to that level to make the change. You can perform a search to locate all the instances of a module and to find the names of the instances.

You can have multiple instances of the same module. When you make a change to the parent module the change is reflected in all of the instances.
