Design of integrated software environment for hardware-in-loop simulation

To describe the software framework adapted for the hardware-in-loop (HIL) simulation, this paper is mostly concerning the all-in-one software environment including: hard realtime simulation on non-dedicated computers, interactive modeling tool, models database, experiment data process and integrated interface to HLA/DIS network. The hard realtime solution is based on the generic personal computers and GNU/Linux operating system, with a common framework to provide realtime network communication, realtime data acquisition & signal output. And as a part of HIL simulation environment, the modeling tool and backend data support are implemented by mature database system and programming language. And, the HLA/DIS interface is designed to perform limited interaction of simulation with other expected simulation entities or logical modules.
