3.5.1.14. Report Route Net of Interest

The Timing Analyzer's Reports > Design Metrics > Report Route Net of Interest... command allows you to report the nets that require the most effort from the router. The report shows the percentage of total router effort for the nets reported. The equivalent scripting command is report_route_net_of_interest.

This report allows you to identify nets that should not require significant router effort. For example, you might expect that low speed management interface nets are not timing critical, and therefore not require much router effort. However, if Report Route Net of Interest reports that some nets in the low speed management interface require significant effort from the router, you can investigate that further. The investigation can determine whether the timing constraints are correct, whether the fan-out is significant and can reduce through driver duplication, or whether the net passes through congested areas.
