Testing control methods for use in current management systems for digital logic devices

Patent Number 7,428,465

Systems and methods for Current Management of Digital Logic Devices are provided. In one embodiment a method for calibrating a digital logic circuit current management system is provided. The method comprises activating one or more synchronous logic paths of a plurality of synchronous logic paths within the digital logic integrated circuit; sampling a voltage powering the digital logic integrated circuit while activating the one or more synchronous logic paths; storing one or more data samples representative of the sampled voltage; and calculating a bypass current setpoint based on the one or more data samples, wherein the bypass current setpoint specifies one or more bypass current characteristic to prevent the voltage powering the digital logic integrated circuit from dropping below a reference voltage.
