Using Insert Attribute

There are 2 ways of using this option. Either pre-select the items that you want to add the attribute to, or deselect everything to enter a mode whereby you can pick the items after using the dialog.

When the option is run you are presented with the following dialog:

If you pre-selected some items, their type is shown in the title bar of the dialog.

Add Attribute To

This is only available if no item was pre-selected prior to entering the dialog. Use it to choose what type of item you will be adding the attribute to. This helps restrict the attribute names list to only appropriate names and tells the system what type of items can be picked when adding the attributes later.

Attribute Name

Type the name of the attribute you wish to add, or use the drop down list to select an attribute name that already exists in the design.

Usage

When a new attribute name is supplied, use this drop down list to select the required usage. The usage list will be restricted to those appropriate to either the pre-selected items or the chosen item types. For existing attribute names the usage shows the value already assigned to it and cannot be changed.

Attribute Value

If you have selected a system attribute name this will show its current value, otherwise you can type in the value you wish to give your attribute. You can also select the option from the drop down list to indicate that you only wish to add an attribute position as a placeholder for an attribute value to be added at some time in the future.

You can also substitute other attribute values or names into your attribute to display a value comprised of several attributes. Use the Substitute Attribute button to paste an attribute name into the value in such a way that it will be replaced with its attribute value when your attribute is added to the design.

The following dialog will be presented to allow you to choose the attribute you want substituted.

Choose the attribute from the list and press OK to have its name pasted into the value field, encapsulated with the correct substitution character.

Visible Attribute Value

Check this option to indicate that you wish the attribute to be displayed in the design by creating an attribute position.

Use Defaults

Keep this box checked to use the default style, etc. as defined on the Attribute Defaults tab. Note that you can define specific defaults for each different Attribute Name. Unchecking the box allows you to set the values to use for the Attribute Position you are about to add.

Placing the attribute
Press OK to start adding the attribute. If items were pre-selected, you will be able to use the mouse to place an attribute on each item. If nothing was pre-selected, you will be prompted to select each item in turn to add the attribute to. In both cases use the Escape key to finish adding and re-enter the dialog.

Special Note About Pin attributes on a Schematic Symbol Pin

You can assign a Net Attribute to a Schematic Symbol pin. However, for this feature to be available, the pin must already on a net. This would have been assigned using the Add To Net option.
