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： Systems for making impedance adjustments that will auto-tune a communication path is disclosed. The method can utilize time domain reflectometry (TDR) to acquire data about impedance mismatches and can adjust the termination impedances based on the acquired data. A system is also disclosed that has an isolator to decouple a first adjustable resistor from a transmission path in a first mode and couple the first adjustable resistor to the path in a second mode. The system can have a test transmitter to create a first current on the path in the first mode and to create a second current having twice the current in a second mode, wherein a detector can detect a first voltage during the first mode and a second voltage in the second mode as the first adjustable resistive load is adjusted in the second mode until it reaches a value matching the first voltage detected in the first mode.
