NAME
timing_report_unconstrained_paths
Specifies if PrimeTime searches for unconstrained paths or not
when you use the report_timing or get_timing_paths command.
TYPE
Boolean
DEFAULT
false
DESCRIPTION
When this variable is set to FALSE (the default), the report_timing and
get_timing_paths commands search only for constrained paths. It runs
much faster if there are lots of unconstrained paths in the design, but
you are not interested in these unconstrained paths.
只在report_timing or get_timing_paths时有效,并不能报出false_path的来源。
