Critical-Cell Optimization replicates cells in failing paths. If the loads on a specific cell are placed far apart, the cell might be replicated with new drivers placed closer to load clusters. High fanout is not a requirement for this optimization to occur, but the path must fail timing with slack within a percentage of the worst negative slack.
