There is a method that can be used in OpenLane interactive mode padframe_gen_batch. There is an example of using it here https://github.com/efabless/caravel/blob/93596a3651699b91f461954c6d7d3140c3aca0e0/openlane/chip_io/interactive.tcl#L36. There are bunch of configuration variables needed here https://github.com/efabless/caravel/blob/chip_io_config_updates/openlane/chip_io/config.tcl. Ultimately the script that's being used is https://github.com/The-OpenROAD-Project/OpenLane/blob/master/scripts/odbpy/padringer.py.

The documentation needs to be updated to reflect that.

Note: You should be using https://github.com/The-OpenROAD-Project/OpenLane not https://github.com/efabless/OpenLane
