1. A method comprising:
generating multiple pulses in a clock enable signal using a shift register circuit in response to a single transition in a
start signal and in response to control signals; and
generating an output signal for testing an electronic circuit using a first multiplexer circuit by selecting from an input
signal and a first clock signal, wherein selection of the first multiplexer circuit is controlled by the multiple pulses in
the clock enable signal.
