@maliberty Two questions:

1. Can you reproduce?
2. Just trying to understand. I found it surprising that "read_db" does not have a -child option. Isn't .odb a binary representation of .def + .lef? If so, I would expect all read_def options to be available with "read_db". https://github.com/The-OpenROAD-Project/OpenROAD/blob/master/src/odb/README.md

For the read_def -child feature it is a bit awkward that the .odb file can't be used.

A feature that is frequently asked for when I show OpenROAD is whether it is possible to double click on the macros to drill into them.

read_def -child would be part of meeting such a seemingly reasonable request.

Still in the queue. The child is stored in the db so there is no need for a similar option on read_db.
