Project Navigator - How to open the ".ucf" file in text editor

Description

I haveattempted to open theUCF by double-clicking on the ".ucf" source, but this opened up the constraints editor.

How do you open the ".ucf" filein text editor?

Solution

In ISE 10 and earlier, a UCF could be opened in the designated text editor by double-clicking on the UCF file in the design view.

In ISE 11 and later, toopen the ".ucf" in the text editor, select the ".ucf" in the Design Hierarchy window and in the processes window, expand "User Constraints" and double-click on "Edit Constraints (Text)".
