Description

technical field [0001] The invention relates to a graphical modeling device and method for an automatic testing system, which is related to the modeling technology of a computer information system and the computer image data processing technology, and belongs to the technical field of automatic testing. Background technique [0002] An automated test system refers to a system that automatically measures the device under test, processes the data, and displays or outputs the test results in an appropriate manner with little or no human participation. Compared with manual testing, automated testing saves time and effort, and can improve labor productivity and product quality. The hardware composition of an automated test system usually includes test instruments, switching systems, main control computers, test connectors, and equipment to be tested. Connect the device to the device under test, apply an excitation signal to the device under test, and measure the output signal of...

Problems solved by technology

[0003]With the emergence of new products, the complexity of the device under test is also continuously increasing, which leads to a dramatic increase in the number of test points that must be connected to the device under test

The sharp increase in the number of test points not only means a sharp increase in the complexity of test instruments, switching systems and test connectors in the automated test system, but also increases the complexity of the signal communication path in the automated test system

[0004] At the initial stage of design, the current automated test system relies on manual experience to design the equipment composition and signal relationship in the automated test system, and manually records and optimizes it. The manual recording method cannot allow other testers to quickly understand the composition of the system, and when the system is large in scale and complex in structure, the model will be difficult to grasp and manage clearly, and it will not be possible for testers to perform automatic testing in a WYSIWYG manner. The model of the system is designed and optimized, and the knowledge of the design method recorded manually cannot be used by the automated test system during the automated test process, and cannot meet the requirements for improving the degree of automated execution in the future
