Abstract
A metastableproof flip-flop receives an input value on a flip-flop input. The flip-flop holds an output value on a flip-flop output. In response to a transition of a clock signal, a transition in the output value occurs. The new output value is the input value formerly received by the flip-flop. In order to make the flip-flop metastableproof, the transition in the output value is delayed when the input value is in a metastable state. When the input value is no longer in the metastable state, then the transition in the output value is allowed to complete.
