High-Fanout Optimization works as follows:

  1. High fanout nets, with negative slack within a percentage of the WNS, are considered for replication.
  2. Loads are clustered based on proximity, and drivers are replicated and placed for each load cluster.

Timing is re-analyzed, and logical changes are committed if timing is improved.

Tip: Replicated objects are named by appending _replica to the original object name, followed by the replicated object count.
