Internal Error: Sub-system: STA, File: /quartus/h/sta_timer_engine_sys.h, Line: 472

Description

Due to a problem in the Intel® Quartus® Prime Pro Edition Software v21.2, you may see this error in the Timing Analysis stage when you use the "report_cdc_viewer" command in a .sdc file.

Resolution

To work around this problem, do not use "report_cdc_viewer" in your .sdc files.

The "report_cdc_viewer" command should be used directly in the Timing Analyzer GUI.

This problem is fixed beginning with the Intel Quartus Prime Pro Edition Software v21.3.
