In custom hardware security, legacy system repair, and advanced reverse engineering, engineers frequently encounter integrated circuits (ICs) with non-standard, highly abbreviated, or entirely proprietary top markings such as "HXJE". In the absence of a direct manufacturer data sheet, standard operational parameters cannot be immediately known. This paper presents a standardized, multi-tiered framework to transition from a physical IC with ambiguous top markings to a functional "reconstructed data sheet." We outline the process of package analysis, boundary scan utilization, X-ray inspection, and curve tracing to map out an unknown silicon device's architecture. 1.
