"This dissertation consists of three papers. In the first paper, a methodology of building an IC model capable of predicting failures for given disturbances at the clock input based on limited or no knowledge about IC internals was developed.

In the second paper, the maximized radiated emissions of the heat-sink/IC structure are predicted up to 40 GHz by creating an equivalent source using the measured electrical field in the gap between the heat-sink and ICs. The electric field is detected by an E-field probe made of an open coaxial cable coated with absorbing material. A numerical model is built in CST microwave studio to obtain the maximized radiated field with the measured field used as a source to excite the heat-sink model. The evaluated maximized radiated field is in good agreement with the measured value; the error is within 6 dB.

In the third paper, a characterization method for converters with stochastic behavior is presented. The averaged and maximized spectrum of the measured voltages and currents are used to create the model. The phase information is obtained using a dedicated reference channel. After the equivalent source was determined, the actual induced noise voltage at the test load was compared to that predicted by the model with averaged and maximized spectrum to estimate its accuracy. The results indicate that the agreement with the direct measurement is within 5 dB up to 100 MHz when the load is within the characterization range"--Abstract, page iv.
