Usage
report_net_timing [-append] [-file ] [-nworst_delay ] [-nworst_fanout
] [-panel_name ] [-stdout]
Options
-append: If output is sent to a file, this option appends the result to that file.
Otherwise, the file will be overwritten
-file : Sends the results to an ASCII or HTML file. Depending on the extension
-nworst_delay : Report worst net delays
-nworst_fanout : Report worst fanout nets
-panel_name : Sends the results to the panel and specifies the name of the new

: 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 TimeQuest 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 TimeQuest-extension substitution rules.
See the help for use_timequest_style_escaping for details.

# 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
