With roots in analog computer systems used for real-time applications where digital computers could not meet low-latency computational requirements, Applied Dynamics International moved from proprietary hardware architectures to commercial computing equipment over several decades. The Real-Time Station (RTS) was Applied Dynamics first entry into using Commercial Off The Shelf (COTS) computer hardware. Included with the sale of the RTS was the Applied Dynamics software package called "SIMsystem". In 2001, version 7.0 of SIMsystem was released. From 2001 to 2006 Applied Dynamics reworked their software and hardware products to make better use of COTS processors, computer boards, open source software technology and to better abstract software components from the hardware equipment. In 2006, Applied Dynamics announced a beta release of the "ADvantage Framework". The ADvantage brand provided an umbrella for the disparate software components that were formerly included in the SIMsystem package and offered a single software environment to support VME, PC-based, and desktop real-time simulation activities.
ADvantage Framework makes heavy use of open source software technology. Open source software components used include:
