The report_high_fanout_nets command analyzes the netlist and reports on the nets with the highest fanout. The command can be run on a post-synthesized, placed, or routed netlist. Before placement, however, the report is unable to convey clock region and SLR information. The report displays the following:

  • Fanout
  • Driver Type
  • Load Types
  • Clock Regions (where applicable)
  • SLRs (where applicable)

The following figure shows an example of the report generated.
