Abstract : Smart Power circuits, used in the automotive industry, are characterized by the integration on one chip of the power parts with low voltage analog and digital parts. Their main weak point comes from the switching of power structures on inductive loads. These inject parasitic currents in the substrate, capable of activating the bipolar parasitic structures inherent in the layout of the circuit, leading to failure or destruction of the integrated circuit.These parasitic structures are not currently integrated into CAD tools nor simulated by SPICE simulators. The extraction of these structures from the layout and their integration into the CAD tools is the objective of the European AUTOMICS project, in which this thesis is carried out.The characterization of the substrate coupling of 2 case study was used to validate theoretical models and compare them to simulations using the new substrate coupling model.
