I encoutered two questions, and need your help.
1.
what is the difference between "high_fanout_net_threshold",
"physopt_hfs_hf_threshold" and "physopt_hfs_mf_threshold" in physical compile ???
2.
while finishing placement in PC, I use "report_constraint -all_vio". In the report, there are many violations in input port high fanout, but when I "report_net" of this net, the fanout is actually 1. After checking the RTL, I found there is only 1 fanout of these input ports. But why?
