Description
Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 21.3 and earlier, the Timing Analyzer may hang if any SDC files contain the load_report command.
Resolution
To work around this problem, add the unload_report command at the end of every SDC file which contains the load_report command.
This problem is scheduled to be resolved in a future release of the Intel® Quartus® Prime Pro Edition Software.
