AUTOMATIC-GENERATION OF REAL-TIME ADA SIMULATIONS FOR SPACE STATION FREEDOM

This paper describes a method to automatically generate real-time simu lations in Ada for use in Space Station Freedom (SSF) Integration, Tes t, and Verification Environment (ITVE). The interface requirements of the ITVE could not be fully met by commercial-off-the-shelf (COTS) too ls; therefore, modifications to the COTS tool were necessary and a too l was developed in-house to meet the required interface. This process is illustrated by generating a Space Station Guidance, Navigation and Control (GN&C) simulation from an engineering block diagram. Moreover, this method can be readily applied to other environments with differe nt types of schedulers or real-time databases.
