Vias are modeled using an analytical formulation for the parallel-plate impedance and capacitive elements, whereas the trace-via transitions are described by modal decomposition. It is shown that the models can be applied to efficiently simulate a wide range of structures. Different scenarios are analyzed including thru-hole and buried vias, power vias, and coupled traces routed into different layers. By virtue of the modal decomposition, the proposed method is general enough to handle structures with mixed reference planes. For the first time, these models have been validated against full-wave methods and measurements up to 40 GHz. An improvement on the computation speed of at least two orders of magnitude has been observed with respect to full-wave simulations.

Highly efficient interconnect models can be used to assist this process by allowing a detailed exploration of the design space and the impact of different alternatives in an early stage. This paper addresses this issue by proposing a parametric and automated framework for analysis of single-ended links across multiple substrates with semi-analytical via and trace models. It is shown that this method can provide rapid estimations (second to minute range) and it is suitable for the analysis of configurations with realistic complexity.
