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 system and method for reducing noise in a multi-layer ceramic package are provided. With the system and method, additional shielding wires are inserted into the reference planes wherever there are no signal vias present. These additional lines in the reference planes force stronger signal interaction with the reference (vdd/gnd) thereby reducing the interaction between the signals in the signal layers. As a result, the noise present in the signals of the signal layers is reduced.

摘要： An integrated circuit substrate is designed and fabricated with a selectively applied transmission line reference plane metal layer to achieve signal path shielding and isolation, while avoiding drops in impedance due to capacitance between large diameter vias and the transmission line reference plane metal layer. The transmission line reference plane defines voids above (or below) the 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. For voltage-plane bearing PTHs, no voids are introduced, so that signal path conductors can be routed above or adjacent to the voltage-plane bearing PTHs, with the transmission line reference plane preventing shunt capacitance between the signal path conductors and the PTHs.

摘要： A method reduces coupling noise and controls impedance discontinuity in ceramic packages by: providing at least one reference mesh layer; providing a plurality of signal trace layers, with each signal layer having one or more signal lines and the reference mesh layer being adjacent to one or more of the signal layers; disposing a plurality of vias through the at least one reference mesh layer, with each via providing a voltage (Vdd) power connection or a ground (Gnd) connection; selectively placing via-connected coplanar-type shield (VCS) lines relative to the signal lines, with a first VCS line extended along a first side of a first signal line and a second VCS line extended along a second, opposing side of said first signal line. Each of the VCS lines interconnect with and extend past one or more vias located within a directional path along which the VCS lines extends.
