False path exceptions (set_false_path) report paths as if the false path was not applied, similar to
report_timing's -false_path option.
The "RF" column in the report output uses a two-letter symbol to indicate the rise/fall transition that
occurs at that point in the path.
Possible "RF" values are:
The "Type" column in the report uses a symbol to indicate what type of delay occurs at that point in the
path.
Possible "Type" values are:
The values of the "-from", "-to", and "-through" options are either collections or a Tcl list of wildcards used
to create collections of appropriate types. The values used must follow standard Tcl or
TimeQuest-extension substitution rules. See the help for use_timequest_style_escaping for details.
Example
# Reports all timing exceptions for a setup analysis.
report_exceptions
# Reports all timing exceptions for a hold analysis.
