get_timing_paths
Usage
get_timing_paths [-detail ]
[-fall_from_clock ] [-fall_to_clock ] [-false_path] [-from ]
[-from_clock ] [-hold] [-less_than_slack ] [-npaths ]
[-nworst ] [-pairs_only] [-recovery] [-removal] [-rise_from_clock ]
[-rise_to_clock ] [-setup] [-show_routing] [-through ] [-to ]
[-to_clock ]
Options
-detail : Option to determine how much
detail should be shown in the path report
-fall_from_clock : Valid source clocks (string patterns are matched using Tcl
string matching)
-fall_to_clock : Valid destination clocks (string patterns are matched using Tcl
string matching)
-false_path: Report only paths that are cut by a false path assignment
-from : Valid sources (string patterns are matched using Tcl string matching)
-from_clock : Valid source clocks (string patterns are matched using Tcl string
matching)
-hold: Option to report clock hold paths
-less_than_slack : Limit the paths reported to those with slack values
less than the specified limit.
-npaths : Specifies the number of paths to report (default=1, or the same value
as nworst, if nworst is specified)
-nworst : Specifies the maximum number of paths to report for each endpoint. If
unspecified, there is no limit. If nworst is specified, but npaths is not, npaths
defaults to the same value as nworst
-pairs_only: When set, paths with the same start and end points are considered
equivalent. Only the worst case path for each unique combination is displayed.
-recovery: Option to report recovery paths
-removal: Option to report removal paths
-rise_from_clock : Valid source clocks (string patterns are matched using Tcl
string matching)
-rise_to_clock : Valid destination clocks (string patterns are matched using Tcl
string matching)
-setup: Option to report clock setup paths
-show_routing: Option to display detailed routing in the path
-through : Valid through nodes (string patterns are matched using Tcl string
matching)
-to : Valid destinations (string patterns are matched using Tcl string matching)
-to_clock : Valid destination clocks (string patterns are matched using Tcl
string matching)
Description
Get a collection of path objects for the worst-case paths.
