Problems solved by technology

Due to mutual incompatibility, each test instrument requires its own proprietary hardware and software components, which cannot be used on other test instruments
In addition, porting a test program from one test instrument to another and developing a third-party solution requires a lot of effort, and even if a third-party solution is developed for one platform, it cannot be ported or reused on another. On one platform, the process of translating from one platform to another is usually complex and error-prone, requiring more effort, time, and increased testing costs

Abstract

A parallel multiplex test system is disclosed. The parallel multiplex test system is used for testing N devices under test (DUTs) in the N isolation boxes via N test signals through N test channels. The parallel multiplex test system comprises a central processing unit and N function-test modules, wherein N is a positive integer greater than one. The parallel multiplex test system requests the function-test modules to take the function-tests for N DUTs according to the test items which have not been tested, so that different function-tests are taken for all of the DUTs simultaneously through different channels.

Description

technical field [0001] The invention relates to a test system and a test method, in particular to a test system and a test method with parallel multiplexing capability. Background technique [0002] A major reason for the high price of test instruments is the proprietary nature of traditional test instrument architectures. Every test instrument manufacturer has several test instrument architectures, which are not only incompatible among manufacturers such as Advantest, Teradyne, and Agilent, but also within the same manufacturer such as Advantest. The launched T3300, T5500, and T6600 series are also incompatible. Due to mutual incompatibility, each test instrument requires its own dedicated hardware and software components, which cannot be used on other test instruments. In addition, porting a test program from one test instrument to another and developing a third-party solution requires a lot of effort, and even if a third-party solution is developed for one platform, it ...
