Abstract: A method in one embodiment creates a model of an authentic IC for use in comparisons with counterfeit ICs. The model can be created by determining a first or initial set of points of interest (POIs) on the simulated physical (e.g., gate level) layout and simulating side channel leakage from each POI and then expanding the size of the POI and repeating the simulation and comparing successive simulation results (between successive sizes of POIs for a given POI) to determine if a solution for the size of the POI has converged. The final POIs are then processed in a simulation that can use multiple payloads (e.g., cryptographic data) over the entire set of final POIs, and the resulting data set can be used to create the model.

Before the alternating current switch is switched on for the inverter, a target value of a common mode voltage between the inverter and ground is calculated based on at least one of a voltage between an alternating current port and ground, a voltage between the inverter and ground and a voltage across the alternating current switch sampled in real time. Then, a compensation power supply arranged between a main circuit of the inverter and ground is controlled to change the common mode voltage to the target value, so that a common mode voltage difference between two ends of the alternating current switch is zero. Subsequently, the inverter is controlled to switch on the alternating current switch.
