Monitoring transitions of a circuit

A circuit comprising:

• a guard trigger circuit comprising:
• a first input node adapted to be coupled to a first state signal;
• a second input node adapted to be coupled to a second state signal;
• and
• an output node adapted to provide a trigger signal, wherein the guard trigger circuit is adapted to:
• determine a state transition in progress based on the first state signal and the second state signal;
• and
• provide the trigger signal based on whether the state transition is in progress;
• a reset synchronizer circuit comprising:
• an input node coupled to the output node of the guard trigger circuit;
• a clock node adapted to be coupled to a clock signal;
• and
• an output node adapted to provide a synchronization signal based on the trigger signal;
• a timeout circuit comprising:
• an input node coupled to the output node of the reset synchronizer circuit;
• a clock node adapted to be coupled to the clock signal;
• and
• an output node adapted to provide a timeout signal based on the synchronization signal;
• and
• a reset requestor circuit comprising:
• a first input node coupled to the output node of the guard trigger circuit;
• a second node coupled to the output node of the timeout circuit;
• and
• an output node adapted to provide a reset signal based on the trigger signal and the timeout signal.
