Applying advanced system simulation techniques to INFOSEC system development

The gate-level system simulation (GLSS) methodology, developed under the demonstration of avionics module exchangeability via simulation (DAMES) program, allows integration of gate-level models to create simulatable system models that reflect actual hardware designs. The virtual integrated systems (VIS) approach expands GLSS to include the use of behavioral models, and allows system software to be developed and debugged. Advanced simulation capabilities that allow systems integration problems to be dealt with early in the design cycle are described. The evolution of advanced system simulation techniques and the way in which the VIS approach can be applied to the development of complex modular information security devices, such as the advanced avionics COMSEC unit (AACU), are described
