The SystemC AMS 2.0 standard [1] published in March 2013 by the AMS Working Group (AMSWG), considerably extends the TDF execution semantics and proposes new language constructs to support dynamic and reactive behaviors. This paper presents two examples detailing the usefulness of Dynamic TDF and showing the dedicated constructs that allow time step variations during simulation. The goal of this paper is to demonstrate how these new capabilities improve simulation accuracy while maintaining a high execution performance by avoiding unnecessary computations.
