Abstract:

In building simulators for training purposes more and more of the simulation activities are being carried out by digital computers. One of the basic problems in checking out a large complex simulator system is the testing and evaluating -- and, where necessary, the correction -- of the computer programs in the simulation computer. As a design tool, this invention contemplates simulating that portion of the entire system which is not usually simulated and providing between the master simulation computer which is normally used in a simulator and the secondary computer which is used only in a system of this invention, an interface which permits the smooth functioning and intercommunications between the two.
