ハードウエア故障シミュレーション機能を有するソフトウエアテスト支援システムの開発

抄録

This paper proposes a software testing support system with the hardware failure simulation functions. In recent years, the high integration of the semiconductor device is advanced by the development of a smartphone and the tablet device. By such reason, a CD-SEM which is a semiconductor device tester using an electron beam needs high precisely and functionality. Software and concurrent development of the hardware are adopted to promote development of CD-SEM. However, a development delay of the software have been becoming big issue. One of the factors is that software test environment of large-scale software comprised of plural computers is insufficient. The software test support system was developed. It has the Real-time OS simulator and a hardware simulator which worked in a virtual machine. Furthermore, a hardware failure simulator is included in the system to make a hardware error stochastically. Herewith, the system works to prevent losing test case that a software engineer does not notice. At first, this article shows a software test support system using a hardware failure simulator. Then, it shows a result that applied the system to software development of CD-SEM.
