Abstract

As we are moving from a traditional software development process to a new development paradigm where the process it largely driven by tools and automation, new challenges for verification and validation (V&V) emerge. Productivity improvements will in this new paradigm be achieved through reduced emphasis on testing of implementations, increased reliance on automated analysis tools applied in the specification domain, verifiability correct generation of source-code, and verifiably correct compilation. The V&V effort will now be largely focused on assuring that the formal specificationsare correct and that the toolsare trustworthy so we can rely on the results of the analysis and code generation without extensive additional testing of the resulting implementation. Most effort has traditionally been devoted to the verification problem. In this position paper we point out the importance of validation and argue that if we fail to adequately address the validation problem problem the impact of verifying code generation and compilation will be limited.
