Coping with evolution in automated production systems implies a cross-disciplinary
challenge along the system's life-cycle for variant-rich systems of high complexity. The …

Programmable logic controllers (PLCs) are heavily used in industrial control systems,
because of their high capacity of simultaneous input/output processing capabilities …

A spurious actuation of an industrial instrumentation and control (I&C) system is a failure
mode where the system or its component inadvertently produces an operation without a …

Context: The goal of specification pattern catalogs for real-time requirements is to mask the
complexity of specifying such requirements in a timed temporal logic for verification. For this …

We present a formal framework to certify k-induction-based model checking results. The key
idea is the notion of ak-witness circuit which simulates the given circuit and has a simple …

Safe separation between aircraft is the primary consideration in air traffic control. To achieve
the required level of assurance for this safety-critical application, the Automated Airspace …

Model checking is a powerful formal verification method that can also be used to evaluate
PLC software. A lot of manual work and some expertise are still needed. Proposed methods …

Embedded system design is a complex process that demands an extensive system level
modeling. Its implementation encompasses software and hardware components and its …

The ability to assess the reliability of safety-critical systems is one of the most crucial
requirements in the design of modern safety-critical systems where even a minor failure can …

This paper discusses the use of symbolic model checking technology to verify the design of
an embedded satellite software control system called the attitude and orbit control system …
