碩士 === 國立臺灣大學 === 電子工程學研究所 === 96 === Worldwide Interoperability for Microwave Access (WiMAX) is a telecommunications technology based on IEEE 802.16, and it provides wireless data in a variety of ways, from point-to-point links to full cellular type access. Protocol Conformance Testing (PCT) is provided by WiMAX Forum for the development of WiMAX. PCT executes the testcases designed in TTCN-3 for estimating whether the devices are designed according to the protocol. However, TTCN-3 core language can’t execute itself, and an integrating testing tool named Software Testing Workbench (STW) is developed to translate TTCN-3 into executable C/C++ code. We address the limitations of the STW, and successfully develop a new code generator for STW to solve the restrictions. We first translate the TTCN-3 core language into a parsing tree by Lex&Yacc. Therefore, the code generator can trace the parsing tree to extract the essential information, and generate the corresponding executable C/C++ code formats. Moreover, our approach enhances the compilation performance and supports more functions for users.
