Advances in High-Speed Real-Time Simulation

The demands of modern applications for ever increasing performance for real-time simulations have posed considerable challenges to simulation developers which are still not fully met. An effective response to these challenges has involved an interesting combination of a return to old-style programming techniques such as multi-rate simulation and low-level program design with a focus on individual machine cycles, with new technologies (DSP, FPGA, cell architecture) and algorithms (state transition, QSS). Some of these possibilities remain to be explored and the prospects for future research are very encouraging.
