class SCH_REFERENCE_LIST
 

Detailed Description

SCH_REFERENCE is used as a helper to define a component's reference designator in a schematic.

This helper is required in a complex hierarchy because a component can be used more than once and its reference depends on the sheet path. This class is used to flatten the schematic hierarchy for annotation, net list generation, and bill of material generation.
