The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
The application provides a pattern file quick issuing method for a burn-in test all-in-one machine, wherein the burn-in test all-in-one machine comprises a PC end and a test end (the test end is the burn-in test all-in-one machine), the PC end generates a pattern total file containing N issuing channels, and the test end analyzes and then stores pattern subfiles of different channels respectively so as to quickly issue pattern subfiles of a plurality of channels simultaneously. Each channel corresponds to a test sub-card, and the test sub-card runs the corresponding pattern sub-file so as to perform performance test or aging test on a plurality of tested elements at the same time.
As shown in fig. 1, the method for quickly issuing N pattern subfiles by the PC end:
step one, a pattern total file processing step: the PC end converts and compiles the pattern total file to obtain vector information and label information, wherein the pattern total file comprises N pattern subfiles, and the vector information corresponds to the pattern subfiles one by one.
The test terminal is provided with N test sub-cards, each test sub-card corresponds to one issuing channel, and the PC terminal edits the pattern total file comprising N pattern sub-files. One embodiment of the application is: after the editing of the pattern total file is finished, the pattern total file is saved as a universal format file (the universal format file can be conveniently converted into any type of file), and the suffix of the universal format file is ". Tptx". And converting the universal format file into a binary file, wherein the suffix of the binary file is ". Patx".
After the pattern total file is converted into a binary file, compiling the binary file and generating a label file and N vector files, wherein one vector file corresponds to one test sub-card so as to store pattern sub-files of corresponding channels respectively later, and acquiring label information and N vector information respectively according to the label file and the N vector files.
Step two, a step of generating issuing data: acquiring file information, timeSet information and PinList information of a pattern sub-file, storing the file information, timeSet information, pinList information, label information and vector information in a first storage format to generate pattern information, and forming issuing data by all the pattern information together.
The file information comprises the generation time of the pattern subfiles and the issuing paths of the pattern subfiles, and different issuing paths correspond to different test subfiles, so that the test terminal issues the pattern subfiles for the second time according to the file information. A kind of electronic device with high-pressure and high-pressure functions: after the pattern subfiles are issued to the test terminals, the secondary issuing is carried out, and the test terminals are issued to the corresponding test daughter cards.
The TimeSet information is used to indicate the time required for running an instruction in the daughter card, the TimeSet can be set manually, and the TimeSet values in different daughter cards are not identical.
PinList information: pinGroup-PinNameList. The pattern subfiles include instructions arranged according to a set sequence, and the PinList information includes all instructions in the pattern subfiles. When the test terminal receives the instructions of the plurality of pattern subfiles at the same time, the instructions of different pattern subfiles are automatically classified according to the PinList information, and the instructions of the same pattern subfiles are classified together.
Vector information for directly recording Pin information (instruction information), and label information for recording storage address corresponding to vector, and downloading the vector according to label information sequence when downloading the pattern subfile to complete the downloading of pattern subfile.
As shown in fig. 3, the pattern information includes a first type code indicating the type of information, first data for recording the information, and a first number of bytes for recording the number of bytes occupied by the information.

The issuing message comprises front-end data recording partition table information so as to store pattern information of different channels in a partition mode according to the analysis codes and the initial addresses in the partition table. The issuing message comprises issuing data for recording pattern information and is used for recording specific pattern information.
One embodiment of the application is: the sending message is sequentially from head to tail as head end data, front end data and sending data. The test end preferably acquires the partition table information, and analyzes and stores pattern information according to the partition table information.
Step five, a step of message analysis is issued: the testing terminal receives and identifies the front-end data of the sending message, quickly analyzes the sending data according to the front-end data, respectively stores pattern information, generates N pattern subfiles and label files, and realizes synchronous sending of the pattern subfiles.
