Removing a Name
A device or signal name can be removed by using the Zap pointer, as
described in the section on Deleting a Device, above. If the signal has been
named in multiple locations, then Zap removes the name only at the loca-
tion zapped.
Editing a Name
The name can be changed by simply clicking the Text pointer on the signal
name and editing it using the keyboard. Alternatively, a name can be edited
by choosing the Name command in the pop-up menu for the device or sig-
nal. Changing the name in the resulting dialog—or at any single location
on the diagram—will change all visible occurrences of it.
Moving a Name
A device or signal name can be moved by activating the arrow cursor,
clicking and holding the mouse button on the name, and dragging it to the
desired new position. Pin numbers cannot be repositioned.
Setting and Editing Pin Numbers
Pin numbers may contain one to four characters. They are always posi-
tioned adjacent to the associated pin. Any characters may be used—not just
digits—in order to accommodate alphanumeric pin numbering for pin grid
arrays.
Uses of Pin Numbers
Pin numbers are used only for labeling purposes and have no particular
connectivity significance to LogicWorks. Pin numbers are not checked for
duplicates or other invalid usage. Pin numbers placed on a diagram will be
used in creating a netlist (see Chapter 13, Creating Text Reports), and will
appear when the circuit is printed. If a pin is unnumbered, it will appear in
a netlist with a “?”—unless the device has three or fewer pins (e.g., discrete
components), in which case it will be sequentially numbered.
