This paper describes an integrated engineering environment developed by BAE Systems which combines an integration and test process called Simulation-Emulation-Stimulation (SES) using physics-based high-fidelity dynamic simulation models. This environment creates real-time vehicle simulations of system and electrical control behavior that enable the visibility of electronic component messages and signals at subsystem and system level. It is used to integrate tactical software and electronic components as well as to test and verify vehicle subsystem and system level requirements and performance. To further enhance the SES environment capability, high fidelity electronics simulation models utilized during integration to extend internal signal visibility and aid troubleshooting. With this integrated environment, vehicle electronics and software integration issues can be identified and resolved in a lab before on-vehicle integration occurs. This significantly reduces overall project risk to both schedule and cost.
