Missing Pin Found in Component Display Mode

Parent category: Violations Associated with Components

Default report mode:


This violation occurs if a pin is found to be missing in one of the display modes for a part.


If compiler errors and warnings are enabled for display on the schematic (enabled on the Schematic - Compiler page of the Preferences dialog) an offending object will display a colored squiggle beneath it. A notification is also displayed in the Messages panel in the following format:

Missing Pin <Identifier> in <DisplayMode> of part <PartName>,


Identifier is used to identify the pin in question. The identifier appears in the format PartLibraryReference-Pin Designator (e.g. DIP14-8)

DisplayMode is the specific graphical representation mode for the part in which the missing pin has been found. A part has a Normal mode and can have up to 255 defined Alternate modes

PartName is the library reference for the affected part.

Recommendation for Resolution

This violation typically arises when an alternate graphical mode is defined for a component, but not all pins specified in the Normal mode have been specified for the Alternate. Not only must there be an identical number of pins between graphical display modes, the pins must be identical in both Designator and Name.

In the source schematic library, copy the missing pins from an existing display mode into the offending display mode for the component. Then pass the change on to placed instances of the component, using the Update Schematic Sheets command. This command is available from the right-click menu associated with the Components region of the SCH Library panel.
