Under future research, we will discuss the extensions necessary for extending this successful technology to more complex source languages and optimizing compilers. Dr. Pnueli's research focuses on the verification of reactive, real-time, and hybrid systems. In his pioneering paper in 1977, Prof. Pnueli proposed to use temporal logic for specification of correctness requirements. He is considered to be the leading authority in formal verification, and was awarded the A.M.Turing award by ACM, the most prestigious award in computer science. He is the author over 100 publications, has served on various program committees and editorial boards, and is on the steering committees of various conferences including the International Conference on Computer-Aided Verification.
Monitoring is performed based on a formal specification of system requirements.
Our framework is to bridge the gap between formal verification and testing. The former is used to ensure the correctness of a design specification rather than an implementation, whereas the latter is to used to validate an implementation. Another salient feature is automatic instrumentation of executable code. The paper presents an overview of the framework and two languages for specifying events and conditions and their three-value logic semantics. These two languages are used to specify what to observe in the program and the requirements that the program must satisfy, respectively.
