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.
