Signal toggling detection and correction circuit

A signal toggling detection and correction circuit comprising:

• a first flip-flop that is configured to output a flop output signal;
• a checker circuit that is coupled to the first flip-flop, and configured to receive a restoration signal that is outputted based on the flop output signal and output a set of checker signals based on the restoration signal, wherein the restoration signal toggles based on a fault in the first flip-flop, and wherein at least one checker signal of the set of checker signals toggles based on one of a group consisting of the fault in the first flip-flop and a fault in the checker circuit;
• and
• a fault monitoring circuit configured to determine whether one of a group consisting of the first flip-flop and the checker circuit is faulty based on the toggling of the at least one checker signal of the set of checker signals, wherein based on the determination that the first flip-flop is faulty, the fault monitoring circuit is configured to correct the toggling of the restoration signal and the toggling of the at least one checker signal of the set of checker signals, and wherein based on the determination that the checker circuit is faulty, the fault monitoring circuit is configured to correct the toggling of the at least one checker signal of the set of checker signals.

A signal toggling detection and correction circuit, comprising:

• a first flip-flop configured to output a flop output signal;
• a checker circuit configured to receive one of a group consisting of the flop output signal and a restoration signal, and output a set of checker signals, wherein one of a group consisting of (i) the flop output signal toggles and (ii) the restoration signal toggles based on a fault in the first flip-flop, and wherein at least one checker signal of the set of checker signals toggles based on one of a group consisting of the fault in the first flip-flop and a fault in the checker circuit;
• and
• a fault monitoring circuit configured to determine whether one of a group consisting of the first flip-flop and the checker circuit is faulty based on the toggling of the at least one checker signal of the set of checker signals, wherein based on the determination that the first flip-flop is faulty, the fault monitoring circuit is configured to correct (i) the toggling of one of a group consisting of the flop output signal and the restoration signal, and (ii) the toggling of the at least one checker signal of the set of checker signals, and wherein based on the determination that the checker circuit is faulty, the fault monitoring circuit is configured to correct the toggling of the at least one checker signal of the set of checker signals.
