Abstract
A reliability detection device includes a control circuit, oscillator circuits, and an output circuit. The control circuit is configured to generate enable signals according to a mode signal. The oscillator circuits output oscillating signals, in which each of the oscillator circuits is configured to generate a corresponding oscillating signal in the oscillating signals according to a switching signal when the mode signal has a first logic value, and generate the corresponding oscillating signal according to a corresponding enable signal in the enable signals when the mode signal has a second logic value, and the switching signal is associated with a functional circuit. The output circuit is configured to output a detection signal according to the oscillating signals when the mode signal has the second logic value, in which the detection signal is to indicate a reliability of the functional circuit.
