    摘要: A method, a system and a computer program product for reducing coupling noise in low loss on-module wires used for connecting module components in electrical circuits/devices. During the design stage, an Enhanced Crosstalk Reduction (ECR) utility identifies interconnect wires as driven/aggressor traces or receiver traces. The ECR utility substantially avoids forward crosstalk in a victim trace by specially arranging driver traces adjacent to the receiver victim trace in order to provide a lower level and saturated level of backward crosstalk. In particular, the ECR utility provided a configuration of wire/trace layers based on one or more of: (a) the crosstalk impact of a trace when positioned in a particular location; (b) the crosstalk impact of the trace upon remaining components based on placement in the particular location; and (c) system component specifications. In addition, the ECR utility reduces crosstalk by providing a configuration of receiver wires and transmitter wires without the use of isolation layers.

    摘要: 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.

    摘要: A first selection of mesh line segments of a mesh layer are of a first width and a second selection of mesh line segments of the mesh layer are of a second width, wherein the second width is greater than the first width. The second selection of mesh line segments of the second width are positioned in parallel to a selection of signal lines in a signal layer that are likely to introduce crosstalk, wherein the widening of the mesh line segments shadowing the selection of signal lines increases the likelihood that the return current associated with the signal will flow in the wider mesh line segment, thereby increasing the likelihood of containing the electromagnetic fields associated with the signal such that crosstalk to other signals is reduced or contained.
