摘要： A design structure embodied in a machine readable medium used in a design process can include apparatus of a semiconductor chip operable to detect an increase in resistance of a monitored element of the semiconductor chip. The design structure can include, for example, a resistive voltage divider circuit operable to output a plurality of reference voltages having different values. A plurality of comparators in the semiconductor chip may be coupled to receive the reference voltages and a monitored voltage representative of a resistance of the monitored element. Each of the comparators may produce an output indicating whether the monitored voltage exceeds the reference voltages, so that the resistance value of the monitored element may be precisely determined.

摘要： Digital testing of an analog driver circuit is enabled using a circuit including a control circuit for generating signals, a differential driver circuit for receiving a differential input signal, amplifying the differential input signal and transmitting a differential output signal, a programmable termination impedance circuit for generating a differential termination impedance at the output node of the differential driver circuit, and a differential receiver circuit for converting the differential output signal to a single ended signal and transmitting the single ended signal. The testing includes skewing a differential output termination impedance, adjusting a differential receiver circuit voltage offset, selecting a differential driver circuit power level, enabling a decoder which activates only one differential driver circuit segment per test sequence, activating a segment, stimulating the differential driver circuit with digital test patterns, receiving differential driver circuit output, converting the output to a single-ended signal, and observing the single-ended signal.
