S-TALIRO is a Matlab (TM) toolbox that searches for trajectories of minimal robustness in Simulink/Stateflow diagrams. It can analyze arbitrary Simulink models or user defined functions that model the system. At the heart of the tool, we use randomized testing based on stochastic optimization techniques including Monte-Carlo methods and Ant-Colony Optimization. Among the advantages of the toolbox is the seamless integration inside the Mat lab environment, which is widely used in the industry for model-based development of control software. We present the architecture of S-TALIRO and its working on an application example.

Embedded computer system architectures are distributed, layered and heterogeneous. Development progresses through a series of model refinements with varying levels of detail in different subsystems. Different requirements models and scheduling methods are used for different functions and equipment. Today there is no single schedulability tool that can analyze all of them. this paper describes an open compositional timing analysis framework that allows developers to select a set of analysistools suited for the different kinds of subsystems in their product lines. the framework compositionally applies the tools so that dependencies between subsystems are taken into account when producing an overall end-to-end timing analysis.

We describe a novel technique for bounded analysis of asynchronous message-passing programs with ordered message queues. Our bounding parameter does not limit the number of pending messages, nor the number of "context-switches" between processes. Instead, we limit the number of process communication cycles, in which an unbounded number of messages are sent to an unbounded number of processes across an unbounded number of contexts. We show that remarkably, despite the potential for such vast exploration, our bounding scheme gives rise to a simple and efficient program analysis by reduction to sequential programs. As our reduction avoids explicitly representing message queues, our analysis scales irrespectively of queue content and variation.

Computers are becoming increasingly ubiquitous in all aspects of our life. It is becoming more and more important to ensure that the software (and hardware) that drives them performs as expected. Verification is one approach to improve quality of software and hardware. Verification attempts to formally prove that programs or systems fulfill desired properties and lack undesirable properties. this is a thriving area of research, and much resources are invested in extending it both in academia and in industry. In this special issue, we introduce four papers on verification selected from the 19thinternationalconference on tools and algorithms for the construction and analysis of systems (TACAS'13).

the method of algorithm error analysis is proposed. It was developed for gimballess inertial attitude systems of moving objects, in particular, for spacecrafts. the method is based on the construction of etalon models of rotation, which approximates the real motion. Application of this approach is demonstrated for a comparative analysis of the errors of specific algorithms. the results of mathematical modeling are given.

LSAT (Logistics Specification and analysis Tool) is a tool for rapid design-space exploration of supervisory controllers that steer the product logistics and orchestrate the behavior in flexible manufacturing systems. LSAT enables lightweight modeling of system resources, system behavior, and timing characteristics. the tool provides various visualizations to explore the controlled system behavior and analysis and optimization techniques to improve the system performance. Compared to existing approaches, LSAT provides concise modeling using languages tailored towards the application domain, with domain concepts are elements of the language. LSAT provides efficient performance analysis by exploiting the structure of the models. In this paper, we describe the rationale for developing LSAT and position it with respect to other performance modeling and analysistools. We illustrate the benefits of LSAT with an example system.
