The Symbol Editor’s Pin List
The pin list box contains a scrollable list of the pin names associated with this device. This
list is derived from the following sources:
 If the symbol was opened from an existing part, then the initial name list will be the
pin names associated with the part.
 If a pin tool is clicked in the drawing workspace, a new name may be added with
the form “PINxx” where xx is a sequential number. This is only done if there were
no unplaced pins in the list.
 If an open LogicWorks circuit is selected as an internal circuit, or a saved
LogicWorks circuit is selected as an external circuit, then the names of the port
connectors in the circuit will be merged with the names in the pin list.
 The Add Pins command (page 149) can be used to create a list of pins to be merged
with the pin names in the pin list.
 The Auto Create Symbol command (page 170) can be used to specify all the pin
names and pin numbers for a device symbol.
When the automatic “show pin name” feature is used, the pin name that appears in the pin
list must be exactly the same as the graphical annotation which appears next to the pin in
the part's symbol. The result is that changing a pin name in the pin list will cause the anno-
tation next to a graphical pin to automatically change. For cases where it is necessary to
show a pin annotation that is different from the pin’s logical name, you can hide the auto-
matic pin name and use a normal text object to add any desired label. See “Showing, Hid-
ing, Editing or Moving a Pin’s Name” on page 160.
Any pin that has been NOT been placed (i.e. it has no corresponding graphical pin object
which appears as part the symbol) will be shown in red in the list. Bus pins are marked in
the list with a bolder pin icon and will be followed by their internal pins.
