Abstract: A method of displaying a net in a CAD layout for an integrated circuit chip includes steps for receiving a netlist of an integrated circuit design, displaying a CAD layout of the netlist, selecting a net segment in the CAD layout, and displaying a physical characteristics list of information items representative of physical characteristics of the net segment.

Abstract: A contactor for providing electrical connections between a device under test and a tester input board. The device under test has first electrical contacts with a first pitch and a first diameter that contact a first side of the contactor, and the tester input board has second electrical contacts with a second pitch and a second diameter that contact a second side of the contactor. The contactor has a sheet of an electrically insulating material with a first surface at the first side of the contactor and a second surface at the second side of the contactor. The first surface and the second surface of the electrically insulating material are substantially parallel one to another. Electrical connectors extend along a length from the first side of the contactor to the second side of the contactor. The electrical connectors are substantially parallel one to another along their lengths.
