Verification of embedded systems has become increasingly important in many industrial domains. Safetycritical embedded systems, such as those developed in aerospace industry, are regularly subject to automated formal verification process. In this paper we extend our tool integration chain of parallel, explicit-state LTL model checker DIVINE and Matlab Simulink tool suit with an improved support of counterexample simulation. In particular, we show how to provide the verification engineer with a direct connection between the error discovered by the model checker and the simulation in Matlab Simulink. This work has been conducted within the Artemis project industrial Framework for Embedded Systems Tools (iFEST).

Component-based software development is an important trend in software engineering. Using this approach, a system can be constructed from a set of individual components (i.e. pieces of software with defined interfaces and functionality). On deployment, components are usually not tested for their correct functionality since this is considered to be implied. Simulation tests are nevertheless often used to determine extra-functional properties and quality of services. However, only models of the components are usually used for such testing. In this paper, we present the SimCo -a simulation framework for testing of real software components in a simulation environment. This enables thorough tests of components without the need to create their (potentially incorrect) models. The SimCo itself is constructed from components as well in order to enable its modularity and usability. The utilization of the SimCo is demonstrated on a case study involving component-based application for the control of a road traffic crossroad.
