We present CSolve, an automated verifier for C programs based on Liquid Type inference. We show how CSolve verifies memory safety through an example and describe its architecture and interface.

Automotive microcontrollers support an increasing number of safety applications and include various safety mechanisms in order to meet the ISO 26262 standard. Derivatives of product families address different market segments and customers with individual safety requirements. Thus flexibility is needed to adjust the overhead introduced by extra safety circuitry to the actual configurations and s...

Many energy and production facilities are operating without clear formal safety requirements, which are considered the base for good process safety management practices. Safety requirements are typically specified during process design based on identified hazard scenarios. This paper proposes a practical framework and methods to systematically synthesize safety requirements based on qualitative...

In real-time systems response to a request from a controlled object must be correct and timely. Any late response to a request from such a device might lead to a catastrophy. The possibility of a task overrun, i.e., missing the deadline for completing a requested task, must be checked and removed during the design of such systems. Safe design of real-time systems running periodic tasks under th...

The application of cyber-physical systems (CPSs) in safety-critical application domain requires rigorous verification of their functional correctness and safety-relevant properties. We propose a practical verification process which enables to conduct safety verification of safety critical CPSs. The verification process consists of (a) a system model construction method, which generates a system...

This paper presents a process for the stepwise refinement of safety code assertions from identified system hazards. The code assertions are intended for use in system safety verification. The development of the safety code assertions increases the feasibility of using code verification tools such as SPARK Examiner in the safety verification of large software-intensive systems. The process is de...

This paper presents a methodology for the verification of reactive multi-agent systems (RMAS). High level of confidence about a safe operation is a mandatory in many reactive applications. Model-checking appear as an adequate tool for the verification of safety properties. However, model-checking can be confronted with the problem of intractable state space sizes. To avoid this kind of limitati...
