ENERGY ANALYSIS FOR DIFFERENTIAL POWER ANALYSIS RESISTANCE

摘要

A first and second set of simulation information of a circuit design may be received. Energy consumption values associated with signals may be calculated for each of the first and second sets of simulation information of the circuit design. The energy consumption values associated with the transitions of the plurality of signals for each time point of a plurality of time points may be aggregated based on when each of the transitions of the signals occurs for each of the first and second sets of simulation information. Furthermore, a possible Differential Power Analysis (DPA) leak may be identified at one of the time points based on a difference in aggregated energy consumption values between the first and second sets of simulation information.
