Critical Issue
Description
When compiling an HPS design, you might see an error message similar to the following:
Error (129001): Input port DATAIN on atom \

This error might appear if you add the HPS component to your top-level system by adding the source .qsys file to the Quartus II project.
Resolution
Use the following standard Qsys system generation flow:
- In Qsys, generate the HPS component subsystem.
- Add the resulting .qip file to the Quartus II project.
Alternatively, upgrade to v13.1.
