The electromagnetic leakage analysis based on arithmetic operation of FPGA

The chips in working state have electromagnetic energy leakage problem. We offer a method to analyze the problem of electromagnetic leakage when the chip is running. We execute a sequence of addition and subtraction arithmetic instructions on FPGA chip, then we use the near-field probe to capture the chip leakage of electromagnetic signals. The electromagnetic signal is collected for analysis and processing, the parts of addition and subtraction are classified and identified by SVM. In this paper, for the problem of electromagnetic leakage, six sets of data were collected for analysis and processing. Good results were obtained by using this method.
