FINGERPRINTING CHIPLETS THROUGH POWER DISTRIBUTION NETWORK

原文（中文）

The present disclosure describes a heterogeneous integration (HI) system including an interposer and a plurality of dies coupled by the interposer. The plurality of dies include a die, a transmitter die, and a receiver die. The transmitter die is configured to provide a test signal to the die to generate a perturbation in a power distribution network (PDN) of the HI system. The receiver die is configured to measure a response signal in response to the perturbation in the PDN and to determine an authenticity of the die based on a machine learning classification algorithm applied on the response signal. The disclosure also describes a method of testing the authenticity of the die and a method of training the machine learning classification algorithm.
