Editing Device Symbols 153
dow.
Attributes defined while in the device symbol editor will be associated with the
part in the library. These will become the default attributes for the part when it is
placed in a circuit.
IMPORTANT: Only attribute fields that have a value are stored with the symbol. When you
save the symbol to a library, any fields with null values are stripped off to save
storage. This has the side effect that you cannot create a “place holder” field
definition in a symbol for future use without putting a value in it.
Some visibility options appear in this version of the attributes box that are differ-
ent from what you will see on a device placed in a schematic:
Always Visible This setting indicates that the select field should always be
made visible on the schematic when the device is placed,
regardless of the visibility setting for this field in the target
design. This setting does not prevent the field from being
removed after the device is placed, it just sets the initial
state.
Default Visibility This setting indicates that we wish to make the field visible
only if it is defined as Visible by Default in the design in
which it is placed.
