Error (16045): Instance "" instantiates undefined entity "<entity name>"

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 17.0, you may see the following errors when using preserved periphery logic in a root_partiton.qdb file

Error (16045): Instance "<instance name>" instantiates undefined entity "<entity name>"
Error (16185): Can't elaborate user hierarchy "<instance name>"
Error (16186): Can't elaborate top-level user hierarchy

These errors can occur if the original project includes child partitions, or if the project includes HSSI IP. The HSSI IP creates a default auto_fab_0 partition.

Resolution

If the instance in the error is a child partition that you have created, remove the child partition.
Otherwise, if the error references the auto_fab_0 partition, contact Altera support.
This problem is fixed starting with the Quartus® Prime Pro Edition Software version 17.1.
