Abstract
A method and device for detecting faults in an electronic circuit, such as a multiplexed latch includes n control inputs, p data inputs, and at least one output. The method involves trying to cause the electronic circuit to function to modify the state of the output with respect to a start state, knowing that if the state of the output effectively changes while the control inputs are inhibited, this means that at least one control input is stuck at logic 1.
