Abstract
A device and a method for generating input control signals of a serialized compressed scan circuit are provided. A control signal generating device receives a test clock signal from a clock input port and a state enable signal from a state enable bus, and correspondingly generates a shift enable signal, a capture enable signal and a strobe signal. A clock gating device is coupled to the control signal generating device, and receives the shift enable signal, the capture enable signal and the strobe signal. When the shift enable signal is enabled, the clock gating device controls the test clock signal as a serialized scan clock signal. When the strobe signal or the capture enable signal is enabled, the clock gating device controls the test clock signal as a scan clock signal.
