ABSTRACT:
Various systems and methods for registering data are disclosed herein. For example, test enabled flip-flop devices are provided. Such devices include a test mode input signal and a register output signal. In addition, the devices include a flip-flop with a data input and a clock input. When the test mode input signal is de-asserted, the flip-flop is operable to register the data input upon a transition of the clock input. Further, the registered data input signal is provided as the register output signal. The devices also include a test circuit with a test data input. The test circuit is operable to provide the test data input signal as the register output signal when the test mode input signal is asserted.
