Developing software that behaves as expected is challenging not just in practice but due to the intrinsic complexity of analyzing software properties automatically. Software analysis offers techniques that can work around these hurdles – guaranteeing correctness, or helping find incorrect behavior. This course describes software analysis techniques, highlights their theoretical underpinnings, and presents tools that make them available in practice to the working software engineer. The presentation includes techniques spanning different levels of correctness guarantees, automation, and applicability. The main topics covered are: axiomatic semantics and deductive verification; static analysis and abstract interpretation; predicate abstraction; and dynamic inference. The course includes assignments where students try out open-source software analysis tools in practice – understanding the trade-offs involved in making software verification technology applicable in realistic settings.
