A method and apparatus for inserting flip-flops in a circuit design between a driver and one or more receiver(s) comprising generating a candidate solution to assign the flip-flop at the node in the circuit, calculating a margin at the driver, calculating the margin at the receiver, and inserting the flip-flop at the node to simultaneously maximize the margin at the driver and the margin at the receiver. Furthermore, the method and apparatus determines whether to insert a second flip-flop at a second node in the circuit, and inserting the second flip-flop at the second node in the circuit such that a delay between the flip-flop and the second flip-flop is substantially equal to a clock period.
