Abstract
Devices, methods, and computer program products for detecting Points Of Failures in an integrated circuit (IC) are provided. The integrated circuit device is described by a structural description () comprising a plurality of elements, the elements representing cells and wires interconnecting the cells, the structural description further comprising portions representing a set of sensitive functional blocks (), each sensitive functional block comprising one or more inputs, at least one sensitive output, and a set of elements interconnected such that the value of the sensitive output is a Boolean function of the input values of the sensitive functional block. The detection device () comprises: The detection device () is configured to detect that said n-tuple represents a Point Of Failure of order n in the integrated circuit (IC) device if the derivative of the Boolean function associated with said sensitive functional block is equal to zero.
