Due to a problem in the Quartus® Prime Pro Edition Software v17.1 Update and earlier, you may see this error message when you are regenerating an IP core using a Platform Designer exported tcl for a standalone IP core.
To work around this problem, manually change all the occurrences of:
"set_interface_port_property <interface> <interface_><port> NAME <value>"
in the tcl script to:
"set_interface_port_property <interface> <port> NAME <value>".
For example, change "set_interface_port_property a a_reset NAME areset" into "set_interface_port_property a reset NAME areset" .
This problem is fixed in Quartus® Prime Pro Edition Software v18.0 release.
