This section provides a summary of all the timing exceptions and clock group constraints. For each constraint type, the number of valid constraints, ignored constraints, number of ignored objects, and number of covered setup and hold endpoints are reported. This table provides more information than the summary table available when report_exceptions is run from the command line (report_exceptions -summary).
To get the detailed information for each exception type, the summary table provides hyperlinks to the Exceptions or Ignored Objects sections. The Valid Constraints and Ignored Constraints link to the same Exceptions detailed table.
Note: An exception is considered ignored when there is
no physical path that connects the
-from, -through, or -to or when
the constraint is totally overridden by another constraint.Figure 1. Report Exceptions: Summary Section
