Singe Reference Rule
There are time when a user would like to highlight just a single placement of a
cell and not all placements of the named cell. To do this first select the
radio button: Single Reference Rule.
Click on the Pick button and using your mouse select an outline from the display. The name of the cell will be displayed and the parent hierarchy (up to the top
level) will be shown. There is no filtering by parent, window or array since
you are selecting only that particular instance of the cell.
