Does the Pairs only option work correctly in Timing Analyzer?

Environment

    Intel® Quartus® Prime Pro Edition
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

No, due to a problem in the Quartus® Prime Pro Edition Software version 24.3, you might see that not all paths are reported when the Pairs only option is enabled. This problem only occurs when reporting multiple corners.

The following reports are affected - 

    get_timing_paths
    report_timing
    report_timing_tree
    report_design_metrics
    report_neighbor_paths
    report_logic_depth
    report_exceptions
    report_timing_by_source_files

The slacks reported in the Timing Analyzer summaries are correct.

Resolution

To work around this problem, don't use the Pairs only option or report just one corner at a time.

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