Due to a problem in the Quartus® II software version 13.0 and later, you may see this error during compilation if you create new design partitions in the Design Partitions Window.
To check whether your design is affected by this problem, examine your Quartus II Settings File (.qsf) and look for any PARTITION_HIERARCHY instance assignments. If the target for this assignment includes the name of the top-level entity of your design, your design is affected and may not compile correctly. For instance, if the top-level entity of your design is chip_top and you intend to create a design partition on instance u0 of module block_a, the following assignment may appear in your .qsf and be incorrect:
set_instance_assignment -name PARTITION_HIERARCHY u0_183c1 -to "chip_top|block_a:u0" -section_id "block_a:u0"To work around this problem, delete any design partitions created within the Design Partitions Window. Re-create the design partitions in the Project Navigator window by performing the following steps:
- In the Project Navigator window, select the Hierarchy tab
- Expand the design hierarchy as necessary to find the hierarchical instance you want to assign as a design partition
- Right-click the hierarchical instance, point to Design Partition on the context menu, and click Set as Design Partition
This problem is scheduled to be fixed in a future release of the Quartus II software.
