Multiple driver errors on Bidirectional pins while using Block-Based design

Hi,

I am using Quartus Pro Prime version 22.2.

I have zero errors when I have only one partition(root partition) on my design. Whenever I add a partition to design, I get multiple driver errors. I think that the problem is bidirectional pins on my parent block which I try to make it partition. How can I create partition with bidirectional pins?

Thanks.

What are the exact errors you are getting?  How are your partitions set up?  All I/O should remain in the root partition and other partitions should include only internal logic.  More detail needed here.

You may checkout the design partition guidelines.

You may share your design .qar so we can investigate further on this. Please share the changes made in design that causes it to fail.

I have a partition (fpga_top) that I want use its final snapshot:

I have bidirectional pins on that partition:

I assign that bidirectional pins on top module (fpga_wrapper):

Synthesize failing in this case:

When "fpga_top" is not a partition, compilation finished successfully. Sharing .qar file.

 

Thanks.
