Abstract: A method for simulating a first computing unit in a second computing unit, wherein software executed in the first computing unit to be simulated is executed in the second computing unit. The method includes determining, by a scheduling module in the second computing unit, a time schedule according to which processes of the software are processed in the first computing unit to be simulated; executing, by at least one simulation module in the second computing unit, the software for simulating the first computing unit, wherein the at least one simulation module performs a predetermined action at a respective predetermined action time point based on the time schedule, in order to obtain an action result; determining, based on the action result, an action time point of a future, in particular next, action; and using the determined action time point for the time schedule.

Abstract: A method for synchronizing a simulation of a simulation model on a computer with a real-time system, the simulation and the real-time system each having a computing clock having a matching macro increment. The method includes the following features: awaiting a message from the real-time system, measuring a receiving instant of the message by the simulation, awaiting at least one further message of the real-time system, measuring the receiving instant of the further message by the simulation; calculating an averaged receiving instant based on the receiving instants of the message and the at least one further message; determining a starting instant of the simulation based on the averaged receiving instant such that the results of a macro increment of the real-time system are available to the simulation at the start of a macro increment.
