A Testable Index Determination Method Oriented to Multi-task Requirements

Abstract

The invention discloses a multi-task-oriented testability index determination method, and aims to provide a multi-task-oriented testability index determination method so that the error of the determined product multi-task testability index is within the allowable range. The technical solution is: first collect relevant data information, then determine the comprehensive performance index requirements of the product, and then determine the relationship between product performance requirements and testability indicators for each stage of the product, and determine the corresponding fault detection rate rFDi and fault isolation rate rFIi and other tests Performance indicators, and finally determine the product test performance indicators required by multi-tasking. Adopting the present invention can continuously circulate and correct while ensuring that the comprehensive performance index requirements of the product are met, so as to obtain the product testability index requirement value of the multi-task requirement of the minimum testability index error ratio, and meet the system comprehensive performance index requirements.

Description

A Testable Index Determination Method Oriented to Multi-task Requirements technical field The invention relates to a method for determining an index in the field of testability engineering, in particular to a method for determining a testability index for multi-task requirements. Background technique Testability refers to "a design feature that a product can promptly and accurately determine its status (workable, non-workable, or degraded) and effectively isolate its internal faults." Testability indicators are parameter requirements that reflect product testability requirements, guide product testability design, and measure product testability levels. Currently, there are more than 100 testability indicators available, and the fault detection rate (r FD ) and fault isolation rate (r FI ) is the most important indicator. Determining testability indicators is the first step in testability engineering. The determination process of testing indicators is generally divided ...

Problems solved by technology

The current testability index determination method is mainly proposed for the single-task requirements of simple products, and is not suitable for products with complex multi-task requirements; when proposing testability index requirements for complex multi-task products, each task requirement is proposed separately The testability index requirements of the product, and finally select the largest testability index requirement as the final testability index requirement of the product

This often results in too high requirements for testable indicators, which makes product testable design more difficult, affects the product research process, and wastes manpower, material resources and other resources.

An effective method is urgently needed to solve the problem of unreasonable product testability index requirements for multi-tasking requirements
