Components Containing Duplicate Sub-Parts

This compiler hint appears when the same part of a multi-part component instance has been placed more than once in a schematic design. For example you have placed a 74HC32 component, with designator U9, but have inadvertently placed two instances of part one of this component, resulting in two instances of U9A in the design. The message is displayed in the Messages panel in the following format:

Component ComponentName has duplicate sub-parts at Location1 and Location2,

where

ComponentName is the name of the offending component in terms of its designator and library reference

Location1 is the X,Y coordinates for the first instance of the particular sub-part

Location2 is the X,Y coordinates for the duplicate instance of the particular sub-part.

Recommendation

Change the part number for the offending parts as required. This can be achieved in one of the following ways:

• Access the Component Properties dialog for the part and change the part number using the available arrow buttons found in the Properties region of the dialog.
• Use the Increment Part Number command - available from the main Edit menu or from the Part Actions sub-menu (when right-clicking over the part). The advantage of launching the command from the Edit menu is that you remain in increment mode, allowing you to cycle through the part numbers until you reach the desired one.
