1. An apparatus comprising:
- a state detector comprising state retention circuits, wherein the state detector is to receive a clock, wherein the state detector is operable to detect logic states of zero and one of the state retention circuits in response to a clock edge of the clock; and
an error detector coupled to the state detector, wherein the error detector is to receive the detected logic states of the state retention circuits, and wherein the error detector is to detect an error in the detected logic states,wherein the state retention circuits comprise a first sequential logic and a second sequential logic, wherein the first sequential logic is to store a first expected logic state, and wherein the second sequential logic is to store a second expected logic state, wherein the first expected logic state is different from the second expected logic state.
