Abstract: For the subsystem RMU (Resource Manage Unit) of new train control system (C4D-I), which is an innovative product without clear technical specification, a method of requirement analysis and test case design based on SCADE is proposed. This method builds models for requirements and test case on basis of SCADE architect modul. It avoids the problems of requirement incomplete, fuzzy and missing caused by traditional manual analysis, and at the same time, the results of requirement analysis provide necessary guarantee for test case design. The test case design method presented in this paper provides a set of test cases in matrix form, which provides preliminary preparation for the automatic generation of test case.

摘要： 针对新型列控系统（C4D-I）的地面核心设备(Resource Manage Unit，RMU)是没有明确技术规范的创新产品，提出基于SCADE需求分析和用例设计方法，该方法以SCADE architect模块为依托，对需求和用例进行建模。该方法避免传统人工进行需求分析带来的需求不完整、模糊和缺失等问题；同时为用例设计提供必要保障。提出的用例设计方法提供一种矩阵形式用例集，为向自动生成用例提供前期准备工作。
