Abstract: According to an embodiment, a cable assembly arranged between a first connector and a second connector is disclosed. The first connector is arranged at a position near a control device on a substrate and the second connector is arranged at a position away from the control device on the substrate. The cable assembly includes a cable row, a paddle card substrate and a hot melt material. In the cable row a plurality of cables each transmitting a differential signal are arranged side by side. The paddle card substrate is provided with signal electrodes and ground electrodes, internal conductors of the plurality of cables are electrically connected to the signal electrodes. External conductors of the plurality of cables are electrically connected to the ground electrodes.

Abstract: An apparatus including processing circuitry configured to: receive an arrangement of a cable path at a given location in a virtual space, the cable path indicating a spatial path in which a cable is to be arranged; receive, from a user, an operation of arranging a first object and a second object in the virtual space, the first object being a piece of equipment having a start point, the second object being a piece of equipment having an end point; and route the cable to two of the pieces of equipment selected from among the plurality of pieces of equipment based on the cable path and positions of the start point and the end point.
