In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen’s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works. Before the final thesis was done the software and hardware models were used separately and for different purposes. The software model wasused for verification and validation, and the hardware model for the system simulator. Because of the complex software it was a requirement to be able to simulate the software and hardware when they were connected, which would make it possible to study the different control signals generated by the software. To do that an interface between the user and the simulation model was created because it takes too much time to set all the inputs to the simulations model. The final thesis was assumed to deal only with an upgrading of the software model. The models have been connected and a user’s interface has been created with help of the program language Mathscript, which is a part of Xmath. A user’s guide is written so the user can simulate without experience of Xmath/Systembuild. With the connected models the us...
