I have a hierarchical schematic, structure as follows

 

Interfaces

    VCO_Top

        V2I

        Mirrors

        WindowFF

 

I want to automatically assign reference designators to U?, C?, etc REFDES properties.

I click Tools -> PCB Interface -> Assign Reference Designators.

 

I get the error

 

  Error 5709:

  Could not open schematic Interfaces

 

Note that "Interfaces" is the name of my root level schematic. If I look at the Interfaces.err file it says

 

  viewbase: Error 222: Error - Could not find WIR file INTERFACES.1.

 

I get a similar error if I choose instead Create Netlist for Layout. The CFG file is the standard Pads94.cfg

 

I see no errors when running Tools -> DxDesignerDiagnostics

 

What does this mean? How do I fix it?
