Encountered here: hdl/conda-eda#60 (review)

Error message:

Traceback (most recent call last):
  File ".../symbiflow/share/symbiflow/scripts/prjxray_create_ioplace.py", line 178, in <module>
    main()
  File ".../symbiflow/share/symbiflow/scripts/prjxray_create_ioplace.py", line 169, in main
    io_place.output_io_place(args.output)
  File ".../symbiflow/share/symbiflow/scripts/vpr_io_place.py", line 151, in output_io_place
    max_name_length = max(len(c.name) for c in self.constraints.values())
ValueError: max() arg is an empty sequence

This can be reproduced by uncommenting the symbiflow_place line in run_sf.sh.
