Abstract: Methods, systems, and computer program products are provided for facilitating cable plugging in a network by receiving, from a scanner associated with the network, wirelessly read connector identifying information from a tag accompanying a cable connector at one end of a cable to be plugged in the network, and using, by a processor, the connector identifying information to ascertain, from a database, applicable cable rules guidance for where to properly plug the cable connector in the network. Based on ascertaining the guidance, one or more indicators associated with one or more plug locations in the network are illuminated to assist in properly plugging the cable connector in the network.

Abstract: One aspect is a method that includes identifying a substantially uniform distribution of signal vias for a multi-layer circuit board based on a design file defining a layout that includes via groups in a two-to-one signal-to-ground via ratio configuration. A signal via pitch is determined as a center-to-center distance between a neighboring pair of signal vias. The signal via pitch is compared to a target minimum drilling distance. A ground via is identified proximate the neighboring pair of the signal vias. Based determining that the signal via pitch of the neighboring pair is less than the target minimum drilling distance, at least one of the signal vias is positioned closer to the ground via such that after the positioning, the signal via pitch of the neighboring pair meets or exceeds the target minimum drilling distance. The design file is modified to include the positioning of the signal vias.

Abstract: One aspect includes identifying via groups that each includes a ratio of a plurality of signal vias to one ground via based on a design file defining a layout of a multi-layer circuit board. A genetic via placement solver iteratively evaluates potential placement solutions that adjust a placement of one or more of the signal vias until at least one solution is identified that meets one or more placement criteria of the signal vias. The genetic via placement solver performs a mutation and recombination of one or more solutions that do not meet the one or more placement criteria and re-evaluates the one or more solutions that do not meet the one or more placement criteria. The design file is modified to include at least one shifted signal via position based on identifying the at least one solution that meets the one or more placement criteria.
