  • In accordance with the development of recent computer technology, railway signaling software became more complex for the intellectualization. Therefore the importance and dependency of railway signaling system on the computer software is getting more increased further, and the testing for the safety and reliability of railway signaling system software became more important. It is started to become influential as very important issue for the reliability and safety of vital embedded software like railway signaling system. The software coding which can have an effect on the safety at the coding level of software shall not be included preferentially, for the safety of software, and must be checked. This thesis suggested an automated testing tool for coding rules on this railway signaling system software, and presented its applied result for railway signaling system software. The testing items in the implemented tool had referred to the international standards in relation to the software for railway system and MISRA-C standards. This automated testing tool for railway signaling system can be utilized at the assessment stage for railway signaling system software also, and it is anticipated that it can be utilized usefully at the software development stage also.

  • Recent advances in computer technology have brought more dependence on software to train control systems. Hence, the safety assurance of the vital software running on the railway system is very critical task and yet, not many works have been done. While much efforts have been reported to improve electronic hardware's safety, not so much systematic approaches to evaluate software's safety, especially for the vital software running on board train controllers. In this paper, we have developed the static software testing tool for railway signaling, especially Fagan Inspection module and checklists supporting module. This static testing tool for railway signaling can be utilized at the assessment phase, and also usefully at the software development stage also. It is anticipated that it will be greatly helpful for the evaluation on the software for railway signalling system.

  • As the requirement of user for robot functionality, the function and interface for controlling the robot system is more sophisticated and complicated. Accordingly development process of robot is more complicated and it takes much longer time to develop a robot system. Software development using project management tool is more important in software engineering because of the complexity of software, especially robot system. This paper proposes SEED (Software Engineering Equipment for Development), which is a web-based and integrated software engineering tool to provide independent tools for robot software development. SEED includes the document management tool, the software configuration management tool, the software testing tool on developing robot software and provide a functionality of collaborated and remote development due to WEB-based operations.

  • Robot software components can be categorized into two types; the pure S/W component and the H/W-related one. Since interface testing of the robot software component is the labour-intensive and complicated work, an effective automated testing tool is necessary. Especially it is difficult to test all types of H/W-related components because it is hard work to prepare all H/W modules related to them. This paper proposes a new simulation-based interface testing automation tool(SITAT) which generates automatically test cases for interface testing of the robot software component and executes the interface test with the generated test cases where the simulator is used for simulation of the activity of a H/W module instead of the real H/W module. This paper verifies the effectiveness of the suggested SITAT with testing of the real H/W-related robot software component.

  • Many railway signalling functions have increasingly depended on computer software with recent development in computing technology, leading to evolution into more flexible and intelligent railway signalling system. Meanwhile, software programs are likely to have many errors and the cost incurred by such errors has increased. Especially, if fatal software error occurs during railway operation, it may result in loss of lives. So the software verification and validation have become more important. It is needed for software functional safety tool to support these, but most commercial tools depend on direct access to the system's memory, resulting in many difficulties in application. Owing to such difficulties and complexity, they are rarely used in railway signalling system software validation. In this study, a new testing tool for software functional testing through an external interface that can be easily used in functional testing of software was developed. Such testing tool allows development and analysis of test cases for black-box testing through analysis of actually used interface protocols, leading to increased user convenience.

  • According to increasing requirments in embedded systems, embedded software has been more complicated then before, a software developer is required to test her/his software to make a efficient embedded system software in both time and space. This paper suggests a testing tool with which a software developer can easily test the embedded system software in cross-development environments. The suggested tool is designed based on host/target architecture, to provide an intuitive test environment in which a test case can be executed in a target board. The tool uses an XML-based test script to generate an appropriate test case. It includes a tree-based test script editor with which a developer can easily make a test case. Therefore, with the suggested tool, a develop can put down a burden on an software testing and get more productivity in software development related on embedded system.

  • One of the activities to improve software quality in ISO 26262 is to apply the design principles for software unit design and implementation mentioned in ISO 26262-6, including the evaluation activity. Before evaluation activity, the tool is compared and selected for evaluation. Because the results of the tool a company selected might have an effect on product quality. In this paper, we suggest the method to compare industrial static analysis tools with some of "MISRA C : 2004 Exemplar Suite" and all lessons learned from comparing tools are described. The result on comparison shows that we just couldn't rely on a result of Static Analysis Tool and need to have another appropriate processes and guidelines to evaluate a software.
