    摘要: An integrated circuit has a plurality of sections, each having a phase detector and a control delay circuit. The phase detector, in response to a phase difference between a reference clock signal and a feedback signal from a portion of a clock grid, controls the delay of its associated clock delay circuit, which, in turn, outputs to the portion of the clock grid. The feedback signal to the phase detector may be connected to an output of a DLL or another portion of the clock grid controlled by a clock delay circuit not associated with the phase detector. Such an arrangement on the integrated circuit leads to clock grid skew reduction.

    摘要: An analog debugging block of an integrated circuit includes a multiplexor, a buffer, and a voltage-controlled oscillator. An analog voltage signal-of-interest is selectively passed through the multiplexor to the buffer. The buffer outputs an analog control voltage dependent on the selected analog voltage signal-of-interest. The analog control voltage serves as an input to the voltage-controlled oscillator and is used to control a frequency of a digital output signal generated from the voltage-controlled oscillator. The digital output signal from the voltage-controlled oscillator is driven off-chip, whereupon a frequency of the digital output signal is determined and compared against a collection of known frequencies that correspond to particular known voltages of the analog voltage signal-of-interest, thereby resulting in a determination of the value of the selected analog voltage signal-of-interest.

    摘要: A method and apparatus for compensating for age related degradation in the performance of integrated circuits. In one embodiment, the phase-locked loop (PLL) charge pump is provided with multiple legs that can be selectively enabled or disabled to compensate for the effects of aging. In an alternate embodiment, the power supply voltage control codes can be increased or decreased to compensate for aging effects. In another embodiment, a ring oscillator is used to approximate the effects of NBTI. In this embodiment, the frequency domain is converted to time domain using digital counters and programmable power supply control words are used to change the operating parameters of the power supply to compensate for aging effects.

    摘要: A temperature monitoring technique that eliminates the need for bipolar devices. In one embodiment of the present invention, a long-channel MOS transistor is configured in a diode connection to sense change in temperature. The diode drives a linear regulator and an oscillator. The oscillator in turn drives a counter, which counts pulses for a fixed period of time. The system clock on the chip is used as a temperature-independent frequency to generate a count. The temperature-dependent frequency is counted for a fixed number of system clock cycles. The present invention eliminates band gap circuitry currently used in most thermal sensing devices to provide a temperature-independent reference.

    摘要: A dual edge-triggered flip-flop that may be programmably reset independent of a clock signal is provided. Using an externally generated reset value, the dual edge-triggered flip-flop may be asynchronously programmed to reset to either a logical high or a logical low. Further, a dual edge-triggered flip-flop that may be set to multiple triggering modes is provided. Using an externally generated enable signal, the dual edge-triggered flip-flop may be set to function as a single edge-triggered or a dual edge-triggered device. Thus, the dual edge-triggered flip-flop may be used multiple types of computing environments.
