Hi pavi622,
Clonning:-let us assume that a cell is driving a fanout of sixty than the output load across output pin of cell will increase this will lead to high dyanamic power disppiation and input tran violation of next cell that is being driven by output load of this cell.So,for that reason we divide the sixty fanout into two parts(thirty,thirty) by keeping two drive strength bufffers such that the power dissipiation will decrease this method is called clonning....,Hope this can help you...,correct me if i am wrong....,

Hi pavi622..,
simply we can say this also as clonning
Cloning is a method of optimization that decreases the load of a heavily loaded cell by replicating the cell.
Buffering is a method of optimization that is used to insert beffers in high fanout nets to decrease the dealy
