Abstract: In one embodiment, a system has an integrated circuit (IC) device, the IC device includes a first processing unit having a first functional block that has a diversifiable sub-circuit and a result output, a second processing unit having a second functional block substantially identical to the first functional block that includes a corresponding diversifiable sub-circuit and a corresponding result output. The IC device includes a comparator adapted to compare the result output of the first functional block to the result output of the second functional block. The diversifiable sub-circuit of the first functional block operates using a first set of operating parameters. The diversifiable sub-circuit of the second functional block operates using a second set of operating parameters different from the first set of operating parameters.
