Arguments | -h | -help | Short help | |
-long_help | Long help with examples and possible return values | ||
-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) | ||
-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. | ||
-panel_name <name> | Report panel_name | ||
-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_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 | ||
-through <names> | Valid through nodes (string patterns are matched using Tcl string matching) | ||

Description | Reports the worst-case paths and associated slack grouped by design entity. Each entity level indicates the worst-case slack and number of paths at that level. Use the "-setup", "-hold", "-recovery", or "-removal" options to specify which kind of analysis should be performed. Use the "-panel_name" option to direct the report to the Timing Analyzer graphical user interface. You can limit the analysis performed by this command to specific start and end points, using the "-from" and "-to" options. Use the "-rise_from" and "-fall_from" options to limit the analysis to endpoints with established high or low starting states. Use the "rise_to" and "fall_to" options to limit the analysis to destination points with high or low ending states. The analysis can be further limited to clocks using the "-from_clock" and "-to_clock" options, or to specific edges of the clock using the "-rise_from_clock", "-fall_from_clock", "-rise_to_clock", and "-fall_to_clock" options. Additionally, the "-through" option can be used to restrict analysis to paths which go through specified pins or nets. Use the "rise_through" and "fall_through" options to limit the analysis to intermediate points with high or low ending states. Use "-npaths" to limit the number of paths to report. If you do not specify this option, only the single worst-case path is provided. Use the "-less_than_slack" option to limit output to all paths with slack less than the specified value, up to the number specified by "-npaths". Use "-nworst" to limit the number of paths reported for each unique endpoint. If you do not specify this option, the number of paths reported for each destination node is bounded only by the "-npaths" option. If this option is used, but "-npaths" is not specified, then "-npaths" will default to the same value specified for "-nworst". Use the "-pairs_only" option to filter the output further, restricting the results to only unique combinations of start and end points. 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 Timing Analyzer-extension substitution rules. See the help for use_timing_analyzer_style_escaping for details. |
