Masters Theses


"In high-speed data communication systems the complexity of link path between transmitters and receivers present a challenge for designers to maintain an acceptable bit error rate. An approach is presented in this thesis to design the link path on a block-by-block basis. The unique advantage of this approach lies on the physics-based model of each block, which then relates performance to geometry and makes design improvement and optimization possible. A tool based on the manipulation of frequency domain data has been designed to help in the design and analysis process of fast communication systems. It accepts as inputs the frequency domain data describing the link path and the time domain signal at the driver, and it outputs an eye diagram at the receiver.

One of the reasons that can cause the degradation of the waveform at the receiver can be referenced to the via transition, needed to switch layer when the high density of the interconnects do not allow to route each single trace on the same layer. The thesis presents a description of a complete model for the multilayer via transition developed starting from the physics of the via geometry. The model is developed by dividing the via geometry in simple parts and describing each element by S-parameter blocks.

A novel technique is developed for connecting S-parameter blocks having an arbitrary number of input/output ports. This procedure is then applied to connect the blocks describing the via geometry, and the final S-parameter data which models the whole via transition geometry is obtained. Finally, this block can be included in the simulation of the overall link and the eye diagram can be obtained relating the effects of the single via transitions to the overall link performances"--Abstract, page iii.
