| Popis: | In order to fit circuit electromagnetic emissions within a spectral mask, a design flow based on high level current modeling for micropipeline circuits is proposed. The model produces a quick and rough estimation of the circuit current, thanks to a Timed Petri Net determining the activation instants of the different micropipeline stages and an asymmetric Laplace distribution modeling the current peaks of the activated stages. The design flow exploits this current estimation for shaping the electromagnetic emissions by setting the controller delays of the micropipeline circuits. The delay adjustment is performed by a genetic algorithm, which iterates until the electromagnetic emissions match the targeted spectral mask. In order to evaluate the technique, an Advanced Encryption Standard (AES) circuit has been designed. We first observed that the obtained current curve fits well with a gate simulation. Then, after shaping the electromagnetic emissions, the simulation shows that the spectrum fits within the spectral mask. |
