Reporting the Scoped Timing Exceptions Being Overridden - 2021.2 English

The second mode of operation of the Report Exception command is to report the list of scoped timing exceptions that are overridden. The report is generated using the -scope_override command line option.

report_exceptions -scope_override

The command line option -scope_override reports the scoped timing exceptions that are partially or fully overridden by top-level constraints. It can, for example, flag IP constraints overridden by top-level user constraints. However, this option does not report the scoped constraints that are overridden by other scoped constraints (either from the same scope or from a different scope).

The report includes, for each overridden timing exception, the following information:

• Constraint position number
• Patterns for the -from/-through/-to command line options
• Type of constraint overriding the Setup and/or Hold
• Scope of the constraint
• A list of position numbers of top-level constraints that are partially or fully overriding the constraint

The following figure shows the Exceptions Report.
