In this paper, we discuss two ways to code DEVS atomicmodels the ям?rst one is based on the switch-case statementin which no phase is described for the atomic model to sim-ulate. The second one is based DEVS-phase design patternin which we objectify phases and transitions. These ways ofcoding are integrated into the LSIS DME tool to generate acomplete compilable code of the DEVS-phase model and apartial code (template) that the user should complete in caseof a DEVS atomic model without phases.
