Abstract
A method and system for performing closed loop simulation of a computer model of a physical system and a hardware component of the physical system is provided. An input waveform for the component from the simulated model of the physical system using an initial waveform as a response waveform of the component is generated at a simulation processor. The input waveform is sent from the simulation processor through a network to a real-time playback and record device (RTPR). The RTPR plays back the input waveform in real time to the component and receives a response waveform of the component and provides the response waveform to the simulation processor. Waveform relaxation (WR) converging methods are utilized at the simulation processor to enable convergence of the generated waveforms affected by hardware induced distortions. A WR method with the generated waveforms are performed to provide a closed loop response of the component.
