Abstract

Simulating the detector response is an essential tool in high energy physics to analyze the sensitivity of an experiment to the underlying physics. Such simulation tools require a detailed though convenient detector description as it is provided by the $DD4hep$ toolkit. We will present the generic simulation toolkit DDG4 using the $DD4hep$ detector description toolkit. The toolkit implements a modular and ﬂexible approach to simulation activities using Geant4. User deﬁned simulation applications using DDG4 can easily be conﬁgured, extended using specialized action routines. The design is strongly driven by easy of use; developers of detector descriptions and applications using them should provide minimal information and minimal speciﬁc code to achieve the desired result.
