Embodiment Construction

[0027] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0028] Before describing the specific embodiments of the present invention, in order to make the solution of the present invention clearer and more complete, the definitions of abbreviations and key terms appearing in the present invention are first described:

[0029] Automatic test system: ATE, Automatic Test Equipment, refers to a system that automatically measures, processes data, and displays or outputs test results in an appropriate manner with little or no human involvement. Compared with manual testing, automatic testing saves time and effort, and can improve labor productivity and product quality. It plays an important role in production, scientific research and national defense.

[0030] like figure 1 As shown, the present invention provides a test path optimization method oriented to the signal of the tested object, comprising the following...

Abstract

The invention belongs to the technical field of path optimization, and particularly relates to a test path optimization method for a tested object signal. Comprising the following steps: S1, acquiring a test file of a tested object in an automatic test system, and constructing a directed graph of the tested object; s2, acquiring a matching test path of the tested object according to the directed graph of the tested object; and S3, detecting the matched test path to obtain an optimal test path of the tested object. According to the test path optimization method, a test file and a sampling file are obtained and compared; constructing a directed graph of the measured object; therefore, a matched test path is obtained; and finally, the matched test path is detected, so that the accuracy and rapidness of the whole test path planning process are ensured.

Description

technical field [0001] The invention belongs to the technical field of path optimization, and in particular relates to a test path optimization method oriented to a signal of a tested object. Background technique [0002] The automatic test system is generally signal-oriented and performs automatic testing. The description of the test points in the test process only expresses the test signal requirements and the test connection ports, and does not specify which test instrument to use. During the execution process, the test instrument needs to test according to the signal. The path is searched and matched. However, the existing test path planning methods mostly focus on reaching the test instrument, but do not consider the optimization and efficiency of the test path. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention proposes a test path optimization method oriented to the signal of the tested object. [0004] The technical sche...
