Event-Based Design Strategy for Circuit Electromagnetic Compatibility

International audienceThis paper describes a method to control the electromagnetic spectrum of an event-driven micropipeline circuit. A mask in the frequency domain is employed to constrain the circuit electromagnetic spectrum. Then a Genetic Algorithm is used to find the required delays of the micropipeline for fitting the electromagnetic spectrum defined by the mask. We observed that the higher emission peak of the asynchronous micropipeline circuit is at least 3.5 times lower than the peak of its synchronous counterpart. Moreover, if the method is applied on an event-driven circuit and not on a desynchronized circuit, better results can be reached
