In the forthcoming file format I would like to avoid the way we currently
handle complex hierarchies using a path of time stamps. Unless you understand
how the time stamp paths work, this:
AR Path="/4B3A1333/4B616B96" Ref="R25" Part="1"
is not human readable. This is the reason that duplicate sheet names is not an
issue with the current design. I'm thinking of using an inheritance design
similar to how the SWEET file format remap component pins for assigning
reference designators and part numbers for components with multiple parts per
package in sheets. I can add a description to the sheet definition in the new
schematic file format specification. I do not want to open up the new
schematic file format discussion again until I finish the initial draft. I
should have this done by the end of September. You can follow the original
discussion by search the mailing list archives for new schematic file format.
After I publish the specification, we can reopen the discussion to finalize the
