Abstract

This work describes a new non-destructive method to determine the presence of anomalies such as Hardware Trojans in physical VLSI layer of FPGA, especially in configurable logic blocks and switch blocks. The detection that accounts for spatially correlated intra-die process variations can be achieved by isolating a suspected region where its device characteristic is inconsistent from ones in the physically nearest regions. This method does not require a golden chip to compare with a chip under test and can be performed without expensive testing equipment. In this paper, we present anomaly implementations and emulations as well as experimental results and analysis on anomaly detection from data obtained from Xili1nx Virtex-4, Virtex-5 and Virtex-6 FPGA devices.
