    摘要: A timing circuit independently controls placement of the positive and negative edges of a periodic signal. This signal may then be used to control a wide variety of integrated circuit applications. The timing circuit includes separate programmable delay lines and a signal processor. Each delay line delays an input clock signal by a different increment of time. The signal processor then generates a timing signal from the clock signal, where the timing signal has a first edge controlled by the first delayed clock signal and a second edge controlled by the second delayed clock signal. The edges may be controlled so that the timing signal assumes different logical values for different amounts of time, thereby customizing the signal to any application. An example of one application includes using the timing signal control switching in a DC-DC converter.

    摘要: An error-detection flip-flop is disclosed for identifying timing errors in digital circuits. The error-detection flip-flop is a master-slave flip-flop including logic to determine whether an input signal is received during a predetermined clock period, signifying a timing error. The error-detection flip-flop produces a variable-length error pulse, which may be combined with other error pulses and converted to a stable signal for sampling by error-correction circuitry. The error-detection flip-flop does not increase the clocking power of the digital circuit and consumes little additional circuit area.

    摘要: Systems and methods are disclosed for measuring signals on an integrated circuit die. In one embodiment, a reference signal is distributed to die locations proximal to the signals to be measured. The reference signal is transmitted over transport paths coupling each of the signals to be measured to the die output. The signals to be measured are transmitted over their respective transport paths and measured at the die output. The relative delay between the signals can be calculated using the reference signal measurements.
