Abstract:
Systems and methods are provided herein for estimating an output current of an input/output (I/O) driver given a set of voltages present at pins of the I/O driver. A set of voltages are received comprising voltages present at a power pin, a ground pin, at least three input pins, and at least three output pins of an I/O driver. Neural network models are applied to one or more voltages of the set of voltages to determine currents associated the I/O driver. A state space model is applied to one or more voltages of the set of voltages to determine another current of the I/O driver. An output current of the I/O driver is estimated based on the currents and the one or more values.
