Some attributes require both a name and a value to be entered. These include LOC and TNM. For a complete list of Xilinx attributes, refer to Chapter 4 of the Libraries Guide.
Follow these steps to add an attribute with a value:
1. Double-click on the net or symbol you wish to place the attribute on. If it is a net, click on the Attributes button.
2. In the "Parameter Name" or Parameters -> Name field, enter the name of the attribute (e.g. LOC).
3. In the "Parameter Description" or Parameters -> Description field, enter the value of the attribute (e.g. P12).
4. Click the Add button. The attribute will appear in the list box.
The number of dots next to the attribute in the list box determines what part of the attribute is displayed on the schematic. Double-clicking on the parameter in the list box will change the number of dots:
0 dots: Neither the Name nor Description will be displayed. 1 dot : The Description only will be displayed. 2 dots: Both the Name and Description will be displayed.

Some attributes only require a name (no value is needed). These include FAST, NODELAY, and X. For a complete list of Xilinx attributes, refer to Chapter 4 of the Libraries Guide.
Follow these steps to add an attribute with no value:
1. Double-click on the net or symbol you wish to place an attribute on. If it is a net, click on the Attributes button.
2. In the "Parameter Name" or Parameters -> Name field, enter the name of the attribute (e.g. FAST). Leave the Description blank.
3. Click the add button. The attribute will now appear in the list box without a value (e.g. "FAST=").
The number of dots next to the attribute in the list box determines what part of the attribute is displayed on the schematic. Double-clicking on the parameter in the list box will change the number of dots:
0 dots: Neither the Name nor Description will be displayed. 1 dot : Only the Description will be displayed (*). 2 dots: Both the Name and Description will be displayed.
(*) In this case there is no Description, so nothing will be displayed.
