Why is the external loopback test failing for the GTS Dynamic Reconfiguration Controller IP in the GTS PMA/FEC Direct PHY example design?

Description

 Due to a problem in the Quartus® Prime Pro Edition software version 25.1.1 and 25.3, you may notice that the external loopback test is not working correctly for the GTS Dynamic Reconfiguration Controller IP for the GTS PMA/FEC Direct PHY example design.  

This is due to incorrect settings in the hardware tcl scripts inside the “hwtest” folder. You may notice the external loopback test shows “DR Test Passed” in the system console; however, it does not change the DR profile for  GTS PMA/FEC Direct PHY IP. 

Resolution

As a workaround, modify the tcl script file as shown below: 

1. Go to “hardware_test_design/hwtest” folder: 
2. Replace the “dr_ctrl_csr_reg_map.tcl ” file inside the “hwtest/src” folder with the attached file. 
3. Replace the “dr_dphy_test.tcl” file inside the “hwtest/tests” folder with the attached file (hwtest.zip).

This problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Edition software.
