The international standard IEC 61131-3, which supports Brad Cox'concept of “Software-ICs”
for industrial control programming, is increasingly being used in safety-related application …

Abstract The goal of System Level Formal Verification is to show system correctness
notwithstanding uncontrollable events (disturbances), as for example faults, variations in …

Simulation-based programmable logic controller (PLC) code verification is a part of virtual
commissioning, where the control code is verified against a virtual prototype of an …

Modern automation systems shall be able to conjugate increasing complexity of controlled
processes with agile production reconfiguration requirements. In such a context, structured …

Many safety-concerned standards and regulations for real-time embedded systems, eg, ISO
26262 for automotive electric/electronic systems, recommends the use of formal techniques …

Simulink is an industrial de-facto standard for building executable models of control systems
and their environments. Stateflow is a toolbox used to model reactive systems via …

Model checking is often applied to verify safety-critical software implemented in
programmable logic controller (PLC) language such as a function block diagram (FBD) …

We report on the use of model checking techniques for both the verification of a process
control program and the derivation of optimal control schedules. Most of this work has been …

In this paper, we present an approach to the interactive verification of statecharts. We use
STATEMATE statecharts for the formal specification of safety critical systems and Interval …
