| Abstract: | A verification and testing environment that includes static analysis, symbolic execution, and dynamic analysis capabilities is presented. Tool integration and co-operation are promoted through use of an intermediate program representation and a system data manager. A substantial user interface aids application of the tools. Their use is guided by a verification and testing methodology on which the system's design is based. The environment has been engineered to support the production of flight control software written in HAL/S. The environment itself is written in Pascal and is designed to be portable. Several development experiences are described. The environment demonstrates that a strong, unified verification and testing environment can be built; it serves as a basis for future investigations. |
