Embodiment 1

[0028] Such as figure 2 As shown, it is a schematic structural diagram of a circuit testing device for a micro-telecom computing architecture in Embodiment 1 of the present invention. The Micro TCA circuit testing device includes: at least one main control board slot 11, at least one advanced daughter card slot 12, and an analog PM unit 13 , switching unit 14 , processing unit 15 and host computer interface 16 .

[0029] The main control board slot 11 is used to insert and fix the MCH, and the advanced daughter card slot 12 is used to insert and fix the AMC. Specifically, the main control board slot 11 and the advanced daughter card slot 12 are both A standard golden finger socket defined in accordance with micro-telecom specifications.

[0030] Preferably, the main control board slot 11 and the advanced daughter card slot 12 can be arranged in parallel horizontally, so that the main control board slot 11 and the advanced daughter card slot 12 do not block each other, which ...

Embodiment 2

[0060] Such as image 3 As shown, it is a flow chart of the circuit testing method of the micro-telecom computing architecture in Embodiment 2 of the present invention, including the following steps:

[0061] Step 201: Insert the MCH and / or AMC into the main control board slot and / or the advanced daughter card slot of the circuit testing device.

[0062] Specifically, in this step 201, only the MCH may be inserted into the main control board slot of the circuit testing device, or only the AMC may be inserted into the advanced daughter card slot of the circuit testing device, or there may be MCH and AMC inserted into the circuit testing device at the same time The conditions of the corresponding main control board slot and advanced daughter card slot.

[0063] Step 202: The circuit testing device confirms that the currently inserted MCH and / or AMC is the MCH and / or AMC according to the detected presence signal of the currently inserted MCH and / or AMC.

[0064] Specifically, t...

Abstract

The invention discloses a circuit test device of a micro telecommunications computing architecture (TCA) and a test method thereof. The test method comprises the following steps: vertically inserting a micro TCA carrier hub (MCH) and / or advanced mezzanine cards (AMCs) into external slots of the circuit test device; simulating the AMCs and / or the MCH by virtue of the circuit test device; and respectively establishing a link between the simulated AMCs and / or MCH and the currently inserted MCH and / or AMCs so as to test functions of the inserted MCH and / or AMCs. In the invention, the external slots of the circuit test device are not obstructed by a case so that the signal integrity of the inserted MCH and / or AMCs can be tested conveniently by a signal test instrument without inserting and extracting the AMCs for times, which solves the problem of reduction of the reliability of golden fingers of the AMCs and avoids the procedure of inserting a large number of the AMCs at the same time so as to simplify the test process.

Description

technical field [0001] The invention relates to the field of micro-telecom computing architecture, in particular to a circuit testing device and method for micro-telecom computing architecture. Background technique [0002] Micro TCA (Micro Telecommunications Computing Architecture, Micro TCA) is proposed by PCI Industrial Computer Manufacturing Group (PICMG) on the basis of Advanced Telecom Computing Architecture (ATCA). Micro TCA is compatible with ATCA's high performance, high bandwidth and the flexibility of Advanced Mezzanine Card (AMC). While creating a very high level of integration, it greatly reduces the cost, system space and scale, and can be easily It can well meet the application requirements in low-end communication, industry, military, medical and multimedia fields. [0003] A typical Micro TCA system includes: 12 AMCs, 1 or 2 main control boards (Micro TCA Carrier Hub, MCH), interconnection backplane, power supply, heat dissipation and other modules. The Mi...
