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_delay <number> | Report worst net delays | |||
-nworst_fanout <number> | Report worst fanout nets | |||
-panel_name <name> | Sends the results to the panel and specifies the name of the new panel | |||
-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. | |||
<name> | Signal or collection name | |||
Description |
Reports delay and fanout information about a net in the design. A net corresponds to a cell output pin. Report can be directed to the Tcl console ("-stdout", default), a file ("-file"), the Timing Analyzer graphical interface ("-panel_name"), or any combination of the three. The value of the name is either a collection or a Tcl list of wildcards used to create a collection of the appropriate type. The values used must follow standard Tcl or Timing Analyzer-extension substitution rules. See the help for use_timing_analyzer_style_escaping for details. |
