Arguments -h | -help Short help
-long_help Long help with examples and possible return values
-append If output is sent to a file, this option appends the result to that file. Otherwise, the file will be overwritten. This option is not supported for HTML files.
-file <name> Sends the results to an ASCII or HTML file. Depending on the extension
-nworst <number> Specifies the maximum number of paths to report for each analysis. If unspecified, there is no limit.
-panel_name <name> Sends the results to the panel and specifies the name of the new panel
-split_by_corner When set, running this command with the -panel option will create a folder containing versions of this report for selected multiple operating conditions. This option has no effect when used with the -stdout or -file options.
-stdout Send output to stdout, via messages. You only need to use this option if you have selected another output format, such as a file, and would also like to receive messages.

Reports net delay analysis results based on set_net_delay commands. Each set_net_delay command is treated as a separate analysis and report_net_delay reports the results of all set_net_delay commands in a single report. The report contains each set_net_delay command with the worst case slack result followed by the results of each edge matching the criteria set by that set_net_delay command. These results are ordered based on the slack value. Use -nworst option to limit the number of lines reported for a set_net_delay command.
