Embodiment Construction

[0035] The term "and / or" in the embodiments of the present application describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can indicate that A exists alone, A and B exist simultaneously, and B exists alone these three situations. The character " / " generally indicates that the associated objects are an "or" relationship.

[0036] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in...

Abstract

The embodiment of the invention provides a product identification information burning test system and method, the system comprises a test computer and a programmable power supply, and further comprises a product identification information PID test control module, the test computer is connected with the PID test control module through a first control line, and one end of the first control line is connected to a serial port of the test computer; the test computer is connected with the programmable power supply through a programmable connecting line; the PID test control module is connected with a board card interface of the tested board card; and the PID test control module is used for receiving the signal / command sent by the test computer, controlling the connection state with the board card interface based on the signal / command, and realizing on-line burning and off-line burning of the product identification information. According to the embodiment of the invention, by adding the PID test control module, the control of online burning and offline burning of the product identification information is realized, and the full coverage test problem and interference problem of the online and offline interface power supply interface are solved.

Description

technical field [0001] The present application relates to the technical field of circuit testing, and in particular, to a testing system and method for programming product identification information. Background technique [0002] The usual circuit board has a product identification information (Product Identification, PID) storage chip, in order to design the needs of PID programming, this chip will have a general hardware circuit design online and offline two modes: 1) online mode, board card After power-on, the PID can be programmed through the processing chip on the board; 2) Offline mode, after the board is powered off, the integrated circuit bus (Inter-Integrated Circuit bus, IIC bus, referred to as IIC for short) ) interface to burn the PID through the offline programmer. [0003] For such interface design, with the existing test mode, part of the test content is often missed. figure 1 It is a schematic diagram of the implementation of the existing test scheme. If t...
