ABSTRACT:
A method of verifying a triple module redundant circuit. The method comprises providing three circuits, each comprising a redundant circuit; coupling a feedback voter circuit at the output of each circuit of the three circuits, each feedback voter receiving the output of each of the three circuits; disabling a first circuit of the three circuits; enabling the first circuit; disabling a second circuit of the three circuits; and verifying the output of the triple module redundant design to determine whether an error has occurred. A article of manufacture for verifying a design implemented as a triple redundancy module is also described.
