DUPLICATE_HIERARCHY_DEPTH

Pushes the last register and some number of registers that precede it in a chain of simple registers down the hierarchy tree of the modules it fans out to, creating a tree with duplicates for each instance at every level of the hierarchy. The registers in the chain must already be present in the design, with no logic in between them and no other fanins/fanouts between them. Value 0 to disable auto-duplication.
