    Abstract: Manufacturing circuits with reference plane voids over vias with a strip segment interconnect permits routing critical signal paths over vias, while increasing via insertion capacitance only slightly. The transmission line reference plane defines voids above (or below) signal-bearing plated-through holes (PTHs) that pass through a rigid substrate core, so that the signals are not degraded by an impedance mismatch that would otherwise be caused by shunt capacitance from the top (or bottom) of the signal-bearing PTHs to the transmission line reference plane. In order to provide increased routing density, signal paths are routed over the voids, but disruption of the signal paths by the voids is prevented by including a conductive strip through the voids that reduces the coupling to the signal-bearing PTHs and maintains the impedance of the signal path conductor.

    Abstract: An apparatus is provided that comprises a plurality of signaling planes providing signal pathways and at least one internal reference plane providing either a voltage or a ground connection. The at least one internal reference plane are provided between at least two of the signaling planes. The apparatus further comprises a signal blind/buried via coupling a signal pathway of a first one of the at least two signaling planes with a signal pathway of a second one of the at least two signaling planes. The blind/buried via runs through the at least one internal reference plane. The apparatus also comprises at least one first conductive feature in the first one of the at least two signaling planes. The at least one first conductive feature is in close proximity to the signal blind/buried via and increases the capacitive coupling of currents in the reference planes of the apparatus.

    Abstract: A method is provided for power delivery analysis and design for a hierarchical system. The method includes building a model corresponding to each element of the hierarchical system, compiling a repository that contains the models corresponding to each element of the hierarchical system, where the repository includes a net list, a domain list, a component list, a pin list, and a layer list. The method further includes performing optimized gridding for each element of the hierarchial system, the net list, the domain list, the component list, the pin list, and the layer list and assembling a system model from the models contained in the repository. Also, the method includes flattening the system model by converting the system model to a flattened system model that consists entirely of resistors, and running a simulation on the flattened system model.
