摘 要：In this paper, we explain how to achieve deterministic execution of FMUs (Functional Mockup Units)under the FMI (Functional Mockup Interface) standard.In particular, we focus on co-simulation, wherean FMU either contains its own internal simulation algorithm or serves as a gateway to a simulation tool. We give conditions on the design of FMUs and master algorithms (which orchestrate the execution of FMUs) to achieve deterministic co-simulation.We show that with the current version of the standard, these conditions demand capabilities from FMUs that are optional in the standard and rarely providedby an FMU in practice.
