A pattern sequence and state transition trigger generator provides a trigger when a specified transition from one pattern/state to another pattern/state occurs in a set of input signals. Decoders detect each specified pattern/state from the set of input signals to produce a prior value and a current value representing the transition. The prior value is slightly delayed and combined with the current value to produce an overlap when the specified transition occurs, which in turn generates the trigger.
