A delay fault testing apparatus includes a scan device having a first input for receiving a data to the core under test, an update device including an input electrically connected to a first output of the scan device, a first multiplexer including a first input electrically connected to the output of the scan device, a second input electrically connected to a first output of the update device, and an output electrically connected to an input of the core under test. The first input of the first multiplexer is switched to the output when a first control signal is asserted so that the output of the scan device is allowed to directly connect to the output of the first multiplexer to launch a transition by switching the first multiplexer rather than triggering an update event, which is restricted to be triggered in the time of a negative edge.
