Virtual evaluation of complex Cyber-Physical Systems (CPS) with a number of tightly integrated domains such as physical; mechanical; electrical; thermal; cyber; etc. demand the use of heterogeneous simulation environments. Our previous effort with C2 Wind Tunnel (C2WT) attempted to solve the challenges of evaluating these complex systems as-a-whole; by integrating multiple simulation platforms with varying semantics and integrating and managing different simulation models and their interactions. Recently; a great interest has developed to use Functional Mockup Interface (FMI) for a variety of dynamics simulation packages; particularly in Commercial Off-The-Shelf (COTS) tools. Leveraging the C2WT effort on effective integration of different simulation engines with different Models of Computation (MoCs); we propose; in this paper; to use the proven methods of High-Level Architecture (HLA)-based model and system integration. We identify the challenges of integrating Functional Mockup Unit for Co-Simulation (FMU-CS) in general and via HLA and present a novel model-based approach to rapidly synthesize an effective integration. The approach presented provides a unique opportunity to integrate readily available FMU-CS components with various specialized simulation packages to rapidly synthesize HLA-based integrated simulations for the overall composed Cyber-Physical Systems.
