In the last decades, there has been a lot of work on formal verification techniques for
embedded hardware/software systems. The main barriere for the application of these …

This paper presents an efficient static analysis for programmable logic controller code. For
each program line (or each function block call), the analysis calculates an over …

Embedded systems often consist of deeply intertwined hardware and software components.
At the same time, they are often used in safety-critical applications, where an error may …

Programmable Logic Controllers (PLCs) are control devices used in industry to control,
operate, supervise, and monitor machines, robots, assembly lines, chemical plants, power …

This paper presents an analysis to infer range and value-set information for programs
operating on programmable logic controllers. Given a program, the algorithm gathers all …

The design of dependable systems must address both cost and dependability (ie safety,
reliability, availability and maintainability) concerns. For large systems, the design space of …

This paper introduces a Boolean and a modular abstraction of programs for programmable
logic controllers in order to make them amenable for formal verification. In the Boolean …

This dissertation is concerned with abstract interpretation of programs whose semantics is
defined over finite machine words. Most notably, the considered class of programs contains …
