Recently, many critical control systems are developed using formal methods. When software applied to such systems is developed, the employment of formal methods in the software requirements specification and verification will provide increased assurance for such applications. Earlier error of overlooked requirement specification can be detected using formal specification method. Also the testin...

To cope with formal verification issues within the ModelDriven Engineering (MDE) paradigm, a separation of duties between software developers is usually proposed: MDE experts define models and transformations, while formal verification experts conduct the verification process. This is often aided by (semi)automatic translations form the MDE elements to their formal representation in the semanti...

Formal modular verification of software is based on assumeguarantee reasoning, where each software module is shown to provide some guarantees under certain assumptions and an overall argument linking results for individual modules justifies the correctness of the approach. However, formal verification is almost never applied to the entire code, posing a potential soundness risk if some assumpti...

This chapter concerns the correct and reliable design of modern security protocols. It discusses the importance of formal verification of security protocols prior to their release by publication or implementation. A discussion on logic-based verification of security protocols and its automation provides the reader with an overview of the current state-of-the-art of formal verification of securi...

There are two main techniques used for RTL validation: simulation and formal verification. The main drawback of simulation is its inability to provide satisfactory design coverage when the number of important scenarios is very large. Formal verification provides exhaustive coverage, but its capacity is insufficient for realistic designs. In this paper we describe our experience with semiformal ...

In deep submicron technology, a large and complex system that has a wide variety of functionalities has been integrated on a single chip. However, it is getting too harder and harder to identify all design bugs in such a large and complex system. If design bugs caused by the initial specification are identified at lower level of abstraction, we are required redesign of the system from the initi...

My primary research interests are in the field of formal methods in computer-aided verification (or Formal Verification for short). This is a relatively young field in computer science which concerns with finding errors in hardware and computer programs, and proving correctness of such designs (absence of certain types of errors). Formal verification is often used in proving correctness of the ...

Despite 20+ years of research on processor verification, it remains hard to use formal verification techniques in commercial processor development. There are two significant factors: scaling issues and return on investment. The scaling issues include the size of modern processor specifications, the size/complexity of processor designs, the size of design/verification teams and the (non)availabi...
