Abstract
An example method of stabilizing a voltage at a device under test (DUT) includes identifying one or more characteristics of a deviation in a first voltage to appear at the DUT. The deviation may result from a digital signal and a concomitant transient current in the DUT. The digital signal may be part of a test flow to be sent over one or more test channels of automatic test equipment (ATE) to the DUT. The one or more characteristics may be identified prior to sending the test flow to the DUT. The method also includes generating a second voltage to apply to the DUT. The second voltage may be based on the one or more characteristics and being shaped to reduce the deviation.
