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

Environment

  • Intel® Arria® 10 FPGAs and SoC FPGAs
  • Intel® Quartus® Prime Pro Edition
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem in the Quartus® Prime Pro edition software version 17.0 and later, 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 Intel support.

    This problem is scheduled to be fixed in a future version of the Quartus Prime Pro edition software.
