Randomized directed testing (REDIRECT) for Simulink/Stateflow models

Abstract

The Simulink/Stateflow (SL/SF) environment from Math-works is becoming the de facto standard in industry for model based development of embedded control systems. Many commercial tools are available in the market for test case generation from SL/SF designs; however, we have observed that these tools do not achieve satisfactory coverage in cases when designs involve nonlinear blocks and Stateflow blocks occur deep inside the Simulink blocks.
