Abstract

A redundancy system includes a first computational device and a second computational device each configured to receive at least one input and to generate a first output and a second output, respectively, based on the at least one input; a random sequence generator configured to generate a random bit sequence; a random delay selector configured to determine a random delay based on the random bit sequence; a first random delay circuit configured to delay outputting the at least one input to the first computational device based on the random delay; a second random delay circuit configured to delay outputting the second output based on the random delay; and a fault detection circuit configured to receive the first output and the delayed second output, and to generate a comparison result based on comparing the first input to the delayed second output.
