摘要： A beacon circuit enabling study of active elements in an integrated circuit is disclosed. The beacon circuit may be integral to a DUT to be tested. The DUT is stimulated by a conventional ATE, so that its active devices are operating. The signal from the active device is sent to the beacon circuit which, in response to the signal, emits light having intensity that is proportional to the value of the signal. In one example, the beacon circuit is constructed as a voltage to current converter having its input connected to the node of interest and its output connected to a current to light converter. In one example, the current to light converter is implemented as a current mirror circuit. One beneficial implementation disclosed is the use of the beacon circuit for the study of voltage supply disturbances.

摘要： Time-resolved emission can be used to measure loop-synchronous, small-signal voltage perturbation in integrated circuits. In this technique the measurements are completely non-invasive and so reflect the true device behavior. The time-dependant propagation delay caused by Vdd modulation also shows the expected qualitative signature. This technique should find applications in circuits with relatively fast clock-like circuits where loop-synchronous voltage pickup is limiting circuit behavior.
