Embodiment Construction

[0012] Please refer to FIGS. 1 to 3, a preferred embodiment of the high-speed peripheral component interconnection bus interface test fixture 10 of the present invention includes a printed circuit board 11 and a plurality of connectors 13, and the connectors 13 are soldered to the printed circuit board 11 and realize electrical connection with the printed circuit board 11. In this preferred embodiment, the above-mentioned bus interface of the north bridge chip 20 applied on a motherboard 22 is taken as an example to illustrate the test fixture and its test process. Since the design specifications of the slots on the motherboard have been determined, the PCI Express X16 specification interface test fixture consists of two sets of eight duplex channels with exactly the same size and specifications. Here, only the first eight sets of channels shown in the figure are used as an example to illustrate .

[0013] The printed circuit board 11 is respectively provided with relevant traces ...

Abstract

A test tool of interconnected bus interface on high speed peripheral component consists of printed circuit board, a numbers of sending signal end connectors being electric-connected to said printed circuit board and a numbers of receiving signal end connectors being electric-connected to said printed circuit board. The said test tool can be used to simultaneously test both sending end and receiving end of interconnected bus interface on high speed peripheral component.

Description

【Technical Field】 [0001] The present invention relates to a high-speed Peripheral Component Interconnect Express (PCI Express: Peripheral Component Interconnect Express) interface test fixture of a motherboard, in particular to a test that can simultaneously perform auxiliary tests on the signal sending end and the receiving end with the above interface Fixture. 【Background technique】 [0002] PCI Express is a new-generation input / output interface specification introduced by Intel Corporation. The purpose is to connect computer systems with peripherals at high bandwidth and speed. Compared with the traditional PCI bus which can only realize one-way transmission in a single cycle, the duplex connection of PCI Express can provide higher transmission rate and quality. [0003] PCI Express introduces switching point-to-point serial transmission technology, and uses serial differential signal interface to adopt point-to-point signal transmission. The so-called differential signal inte...
