High Fanout Nets: Some nets other than clock nets is called HFN.

Ex: Reset, Scan Enable etc.

During synthesis, We set set_max_fanout to some number. i.e. we are telling the synthesis tool to that more than the max_fanout number treat it as High fanout net , so the tool knows and buffers the nets.
