Report Exceptions and Exceptions Reachability

The Timing Analyzer's Reports > Constraint Diagnostics > Report Exceptions... command allows you to report all exceptions to default timing analysis conditions, as specified by the Set False Path, Set Multicycle Path, Set Minimum Delay, or Set Maximum Delay commands (and the corresponding Tcl commands: set_false_path, set_multicycle_path, set_min_delay, and set_max_delay.)

Similarly, you can click on Reports > Constraint Diagnostics > Report Exceptions Reachability... to report the scope of exception constraints in your project. This report allows you to determine whether constraints apply fully or partially, are overridden, and whether the source and destination node are reachable for the constraint by providing a "reachability" percentage. Reachability is the percentage of paths to which the constraint applies. Low reachability indicates a constraint that may be too broad, potentially covering many unrelated items. High reachability indicates that the exception is very targeted.
