Editing Symbol Attributes
You can add attributes (properties) to a symbol. When
you add an attribute, you specify a name and a default
value. This value can be changed when the symbol is used
on a schematic. You can specify whether or not to display
the attribute.
There are two attributes that are automatically added to
symbols that are created.
• The REFDES attribute, whose default value is U?,
specifies the reference designator pattern to use in the
schematic editor.
• The PART attribute displays the symbol’s name.
Note When the symbol is placed on the schematic, PSpice Schematics
automatically fills in the value of the PART attribute to be the name
you used to place the symbol. For example, if the symbol has
several aliases, it fills in the alias that you used. Therefore, you can
assign a value in the symbol editor and use it to place the text on
the symbol, but when the symbol is used, the value will be
reassigned.
