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
