Patent ID: 8126691

Claim:
A graphical modeling system comprising: at least one computing device including: a memory used in a running of a simulation of a model from a zero time point initiating the simulation to a designated time point during the performance of the simulation; a simulation environment having a mechanism for saving and retrieving simulation state and simulation context associated with a simulation of a time-based model, the mechanism to saving the simulation state and the simulation context at the designated time point, the saved simulation state representing mathematical state values from the simulation at the designated time point, the saved simulation context including at least one of a solver variable or zero crossing information from a time in the simulation prior to the designated time point, the mechanism further retrieving the saved simulation state and simulation context for use in initiating a new simulation; and a storage location holding the stored simulation state and simulation context; initiating a new simulation, the new simulation using the retrieved simulation context and a display device displaying a GUI for the simulation environment.
