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 technique for adjusting a communication system involves a link, where the link includes a data line arranged to transmit a data signal and a clock line adapted to transmit a clock signal. The technique uses one or more counters to test the transmission across the link. Dependent on one or more of these counters, a test circuit, connected to the link, compares a known test pattern signal to a latched test pattern signal transmitted on the data line. The test circuit includes an adjustment circuit arranged to generate an adjustable clock signal from the clock signal, where the adjustable clock signal determines when to latch the transmitted test pattern signal The test circuit adjusts a timing of the adjustable clock signal relative to the data signal of the link.

摘要： A method and apparatus for post-fabrication calibration and adjustment of a phase locked loop leakage current is provided. The calibration and adjustment system includes an adjustment circuit that adjusts a leakage current offset circuit to compensate for the leakage current of a capacitor. The capacitor connects to a control voltage of the phase locked loop. Such control of the leakage current in the phase locked loop allows a designer to achieve a desired phase locked loop operating characteristic after the phase locked loop has been fabricated. A representative value of the amount of compensation desired in the leakage current may be stored and subsequently read to adjust the phase locked loop.

摘要： An apparatus for compensating for the effects of resonance in an integrated circuit's power distribution network is provided. A resonance detector monitors transmissions from the integrated circuit for certain bit patterns that may excite the power distribution network at a specific frequency and cause power supply resonance. Power supply resonance causes an increase in power supply impedance. When offending transmissions are detected, the resonance detector activates a damping element on the integrated circuit which dampens the resonance. The damping element is a resistive device between two power supply lines that decreases power supply impedance when activated.
