High-Fanout Optimization works as follows:
- High fanout nets, with negative slack within a percentage of the WNS, are considered for replication.
- 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
_replicato the original object name, followed by the replicated object count.
