Why do the debug toolkits print additional debug messages or stop printing messages in other cases?

Due to problems in the Intel® Quartus® Prime Pro Edition Software version 20.2, the debug toolkits (for example, the Intel® Stratix® 10 EMIF Unified Calibration Debug Toolkit) may print additional debug messages (including duplicate messages) which can be ignored. In other cases, the debug toolkits may print messages but then stop printing messages if the same design changes.

To work around these problems in the Intel® Quartus® Prime Pro Edition Software version 20.2, download the Intel Quartus Prime Pro Edition Software version 20.2 patch 0.25. You must install the Intel Quartus Prime Pro Edition Software version 20.2, prior to installing the following patch:

• Version 20.2 patch 0.25 for Windows (.exe)
• Version 20.2 patch 0.25 for Linux (.run)
• Readme for the Intel Quartus Prime Pro Edition Software version 20.2 patch 0.25 (.txt) 

This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software version 20.3.
