Storage device and method for single-board testing information

Abstract

The invention provides a device for storing the veneer test information and a method thereof. The device comprises a nonvolatile storage unit used for storing the veneer test information from the veneer and ensuring the impossibility of the data loss when the power-down happens, a control processing unit used for providing the read-write function of the nonvolatile storage unit and the control function of a communication interface unit of a host computer and the communication interface unit used for realizing the transmission of the test information between the host computer and a lower computer. The advantages of the invention are in that: 1. the veneer test information can be stored in the veneer and the correctness and uniqueness of the test information are ensured. 2. the test information can be acquired conveniently and the acquisition mode is flexible. The test information can be reported to the host computer to carry out the query through the communication interface and also can be directly read to carry out the query through the veneer software. The invention is suitable under a plurality of conditions such as the production test management, single board repair, on-site equipment maintenance, etc. and is not restricted by the network and the database software. 3. the contents of the stored information are complete so as to be convenient for the information analysis.

Description

technical field [0001] The invention relates to the testing field, in particular to a single board test information storage device and a single board test information storage method. Background technique [0002] In the field of production testing, board test information is very important. Through the analysis of board test information, you can know the status of board test completion and board function realization, which is useful for production test management, board maintenance, and equipment deployment and maintenance personnel. great help. [0003] The board function test generally adopts the method that the host computer sends test commands to the board through the communication port. After the board test is completed, the result is reported, and the host computer judges the test result of the board. For the test information, it is generally processed by the host computer and sent to the server to be stored in an online database. [0004] One limitation of this metho...

AI Technical Summary

Problems solved by technology

If there is an operation error or error in the input link of this logo during the test operation, the test information of the board cannot be correctly found in the database

[0006] Another limitation of this method of storing test information is that it is impossible to determine whether the board has been tested

In the test information of the database, because it is impossible to distinguish whether the board identification information is entered incorrectly or not, it is impossible to judge whether a board is tested.
