A circuit is designed with a delay circuit (,) coupled to receive a clock input signal (CLK) and a control signal (DFT). The control signal has a first logic state and a second logic state. The delay circuit produces a clock control signal (*CLK) at a first time in response to the first logic state and at a second time in response to the second logic state. A clock circuit (,) is coupled to receive the clock input signal and is enabled by the clock control signal. The clock circuit produces a first clock pulse signal having a predetermined width in response to a first transition of the clock input signal and produces a second clock pulse signal having the predetermined width in response to a second transition of the clock input signal.
