Abstract
A fault detection system includes a state register, an error detection code (EDC) register, logic circuitry, an EDC generator, and an EDC checker. The state and EDC registers store first reference data and first checksum data, respectively. The logic circuitry executes a logic function based on the first reference data to iteratively generate second reference data that is different from the first reference data, and updates the first reference data of the state register with the second reference data of one iteration. The EDC generator iteratively generates second checksum data based on the iteratively generated second reference data and updates the first checksum data of the EDC register with the second checksum data of one iteration. The EDC checker detects a fault in the IC based on the updated first reference data and the updated first checksum data.
