ABSTRACT:
Systems and methods are disclosed for monitoring a voltage supplied by a voltage regulation module to a processor in response to a dynamic VID generated by the processor. In one embodiment, a voltage monitoring system monitors the voltage generated by the voltage regulation module to ensure the supplied voltage is within regulation thresholds. The voltage monitoring system acquires an analog reading of the supplied voltage and converts it to a digital value. If the VID changes during the conversion, the result of the A/D conversion is discarded. If the VID does not change, the voltage monitoring system accepts the result of the A/D conversion and compares the supplied voltage to the voltage expected in response to the VID. The voltage monitoring system may compute the error between the actual and expected voltage for each accepted A/D conversion. These errors may be accumulated and averaged. The accumulated error may be compared with regulation thresholds, such as a predefined allowable margin of error. If the accumulated error exceeds regulation thresholds, an alert may be generated and action may be taken depending on the degree and severity of the accumulated error.
