Hi Peter,
Does the value of CAVLIST-001 contain the PIN names in the connector ? If so, current Saber Netlister is not capable to process it. You may have to write your own plug-in to populate the connector information into pin before generating the netlist.
Do you have the write access to the design? Your customer may have to run the plug-in if you do not have write access to your design.
Please let me know if you need further assistance.
Regards,
