Eidetics Corporation has developed the next generation approach to integrated avionics systems testing with its High Fidelity Avionics Software Test System (HI-FAST). HI-FAST is currently in operation in international applications and at Edwards Air Force Base, Edwards, CA. HI-FAST provides multiple bus avionics operation and testing in real-time. The system's aircraft simulation models are high fidelity, allowing software testing under both systems and aircraft dynamic conditions.

A major feature of HI-FAST is the Man-Machine Interface. Through a set of user friendly, menu-driven panels, the user can control, modify and observe every aspect of the simulation.

HI-FAST has real-time monitoring and plotting of packed and unpacked data. Data can be collected and stored from shared memory and from multiple MIL-STD-1553 multiplex busses. The data can be stored in data reduction, weapon scoring, playback and mission debrief formats.

The aircraft's environment includes all atmospheric effects of temperature, altitude, wind gusts and turbulence, and also includes interactive hostile / friendly aircraft and ground targets. This allows Unit Under Test testing under realistic stress conditions.

The system library contains a large number of avionics and system models. The software interface between these models, the airframe and the unit under test, is the equivalent of a MUX-BUS Interface Control Document which is resident in reflective memory. An ICD development tool automatically converts the aircraft level ICD into the form required to pack and unpack I/O data.

A comprehensive data reduction and analysis tool allows multi-variable tabular and graphical presentation of any selected data range and can perform statistical, sort and filtering operations on this data.
