A method is provided for eliminating hold time violations in implementing high-speed logic circuits specified in circuit configuration data includes the steps of providing a synchronizer flip-flop device or latch corresponding to every flip-flop device or latch specified in the circuit configuration data. The synchronizer flip-flop is provided immediately upstream in the data path from its corresponding original user flip-flop device. A predetermined amount of delay is added to the user's original clock and data signals. A synchronizing clock signal generator provides a delayed synchronizer clock for each master clock in the circuit which is provided to each user flip flop.
