OrCAD Capture includes a Property Editor that allows you to view, edit and add properties to objects in a project.
Using the property editor, you can edit properties for instances or occurrences of:
- Parts (including hierarchical blocks)
- Nets (including constituent nets within buses)
- Pins
- Title blocks
- globals
- Ports
- Aliases
Each column in the property editor is a property. Each row is an instance or occurrence. Occurrence rows appear in yellow below their associated instance row. They only appear if you expand the instance by clicking the plus sign (+) to the left of the instance name, or if an occurrence property of an object is different from the instance. The cells in the property editor show the property values for each instance or occurrence. If a white cell contains hash marks, the corresponding property does not have an instance value causing the library definition of the property to "shine through" to the instance. If a yellow cell contains hash marks, the corresponding property does not have an occurrence value, causing the instance value to "shine through" to the occurrence.
The properties that appear in the property editor depend on the items selected in the schematic page. Also, these properties depend on the tab selection at the bottom of the property editor. For example, if the Parts tab is active, the properties for selected parts appear in the property editor.
Note: When you first start the property editor, all instance properties appear. Occurrence properties appear only if they have their own values assigned to them (independent of the instance property values).
You can also constrain the set of displayed properties by using the filters available in the drop-down list in the upper right of the property editor. A number of filters are available. These filters are sets of properties that are typically useful for particular project types. For example, the Actel Designer Part/Net Properties filter includes properties that are useful for constraining a PLD project for integration with Actel Designer software. The <Current properties> filter causes the property editor to display all properties that currently exist for the selected item.
When editing properties in the property editor:
- Property values that are applied to instances will "shine through" to all occurrences of those instances, unless an occurrence has a value (independent of the instance value) for a particular property.
- Occurrence property values override instance property values.
- When you delete an instance property, that property will no longer "shine through" to its occurrences.
- Deleting a property value from an occurrence causes the instance property value to "shine through" to that occurrence.
- Library definitions will "shine through" to the instance and occurrence of the object only if the instance or occurrence value is unedited.
