Tcl Package and Version

Belongs to ::quartus::sta

Syntax report_net_timing [-h | -help] [-long_help] [-append] [-file <name> ] [-nworst_delay <number> ] [-nworst_fanout <number> ] [-panel_name <name> ] [-stdout] [ <name> ]
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

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.

Example Usage
project_open <design>

# Show delay and fanout information for all nets
# that match "abc*"
report_net_timing [get_nets abc*]

# Report delay and fanout information for the 10
# nets showing higher delays
report_net_timing -nworst_delay 10

# Report delay and fanout information for the 10
# nets showing higher fanout
report_net_timing -nworst_fanout 10
