Arguments | -h | -help | Short help | |
-long_help | Long help with examples and possible return values | ||
-data_delay | Report only paths that are covered by a data delay assignment | ||
-detail <summary|path_only|path_and_clock|full_path> | Option to determine how much detail should be shown in the path report | ||
-fall_from <names> | Valid sources (string patterns are matched using Tcl string matching) | ||
-fall_from_clock <names> | Valid source clocks (string patterns are matched using Tcl string matching) | ||
-fall_through <names> | Valid through nodes (string patterns are matched using Tcl string matching) | ||
-fall_to <names> | Valid destinations (string patterns are matched using Tcl string matching) | ||
-fall_to_clock <names> | 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 <names> | Valid sources (string patterns are matched using Tcl string matching) | ||
-from_clock <names> | Valid source clocks (string patterns are matched using Tcl string matching) | ||
-hold | Option to report clock hold paths | ||
-intra_clock | Only report paths whose launch and latch clock are the same | ||
-less_than_slack <slack limit> | Limit the paths reported to those with slack values less than the specified limit. | ||
-npaths <number> | Specifies the number of paths to report (default=1, or the same value as nworst, if nworst is specified. Value of 0 causes all paths to be reported but be wary that this may be slow) | ||
-nworst <number> | 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 <names> | Valid sources (string patterns are matched using Tcl string matching) | ||
-rise_from_clock <names> | Valid source clocks (string patterns are matched using Tcl string matching) | ||
-rise_through <names> | Valid through nodes (string patterns are matched using Tcl string matching) | ||
-rise_to <names> | Valid destinations (string patterns are matched using Tcl string matching) | ||
-rise_to_clock <names> | 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 <names> | Valid through nodes (string patterns are matched using Tcl string matching) | ||
-to <names> | Valid destinations (string patterns are matched using Tcl string matching) | ||
-to_clock <names> | Valid destination clocks (string patterns are matched using Tcl string matching) | ||
Description | Get a collection of path objects for the worst-case paths. This command behaves the same as the report_timing command. However, instead of reporting the paths, it returns a Tcl collection of path objects. You can retrieve path object data using the get_path_info and get_point_info commands. For help on the options shared with report_timing, see the report_timing help page. |
