Abstract
An embodiment of the present invention is a technique to monitor on-die device power grid. A sensor circuit generates a ground reference (GR) signal and N power reference (PR) signals forming a ladder according to a programmable configuration. The GR signal tracks a device ground signal of a device and the PR signals track a device power signal of the device. A comparator circuit compares the GR signal with the N PR signals to provide N comparison output signals, the N comparison output signals indicating position and time that the GR reference signal moves across the ladder.
