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.
The command line option
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
The report includes, for each overridden timing exception, the following information:
- Constraint position number
- Patterns for the
-tocommand 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
