report_net_delay
Usage
report_net_delay [-append] [-file ] [-nworst ] [-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 : Specifies the maximum number of paths to report for each analysis. If
unspecified, there is no limit.
-panel_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.
Description
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.
Example
project_open my_project

update_timing_netlist
set_net_delay -min 0.160 -from [get_pins inst9|combout] -to \
[get_pins *|dataf]
set_net_delay -max 0.500 -from inst8|combout
