Abstract
Existing methods have attempted 2D reconstruction of current for individual layers but not for 3D Integrated Circuits (ICs) non-invasively. Hence, embodiments of present disclosure provide a method and system of reconstructing electric current from 2-D magnetic field maps of 3D ICs. Initially, magnetic field maps of the 3D IC are measured from a certain distance using a sensor. The volume of the 3D IC is discretized into a multiple layers of equal width. Among these layers, the layers having a current flow are detected by firstly calculating current density maps associated with each of the layers using an iterative optimization technique, computing quality measures for each layer based on the current density maps and then eliminating the layers having the quality measures less than a predefined threshold value. Once the layers having current flow are detected, the current density maps for these layers are estimated using the iterative optimization technique.
