report_net_timing
Usage
report_net_timing [-append] [-file <name>] [-nworst_delay <number>] [-nworst_fanout
<number>] [-panel_name <name>] [-stdout] <name>
Options
-append: If output is sent to a file, this option appends the result to that file.
Otherwise, the file will be overwritten
-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 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.
Example
project_open <design>
create_timing_netlist
# 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
