Claim:
1. A method of detecting irregular high current flow within an integrated circuit (IC) device, the method comprising: obtaining infrared (IR) emission information for the IC device; identifying at least one functional component of a plurality of functional components within one or more functional modules of the IC device, the at least one identified functional component comprising a high current flow, based on the obtained IR emission information; obtaining IR emission information for a plurality of reference components, wherein each of the plurality of reference components comprising different IR emission spectral properties, the different IR emission spectral properties corresponding to IR emission spectral properties of different ones of the plurality of functional components, wherein the plurality of reference components formed within a reference module of the IC device, and wherein each of the plurality of reference components having individually configured bias conditions that correspond to bias conditions of a different one of the plurality of functional components; and determining whether the high current flow of the at least one functional component comprises an irregular high current flow based on a comparison of respective IR emission information for the at least one functional component and a corresponding one of the plurality of reference components.
