Hi- I am working on a design with a filter circuit that is used multiple times. I have a single block representing 1 instance of the circuit (1 in 1 out). On the top page of the schematic I have this block copied 4 times- and each block descends to the correct schematic page with the filter circuit on it. My issue is that when I open the part manager, I have multiple instances (4X) of the same reference designator. Obviously I am doing something wrong and I cannot locate much information on how to set the block up so it creates a new set of designators of each instance.
To correct the existing annotation, select the DSN file entry in the Project Manager pane and use Tools>Annotate, set the Action to "Unconditional" update, the Mode to Occurrences (should be "preferred" at this point) and left-click>OK. To keep the design automatically annotated, go to Option>Preferences, Miscellaneous tab and, in Auto Reference, set Automatically reference and Design Level.
