Abstract

Model-based design methodologies such as Simulink/ State-flow, that are based on the synchrony assumption, are widely used in many safety-critical application domains including avionics and automotive systems. The synchrony assumption asserts that actions (such as the execution of code) occur instantaneously. However, actual platforms obviously do not satisfy the synchrony assumption. This paper considers the problem of obtaining resource-efficient implementations of programs that are written under the synchrony assumption on actual platforms, such that these implementations execute in a manner that is semantically consistent with the execution sequences that would occur if the synchrony assumption were to hold.
