PURPOSE:To return to a simulation processing at an arbitrary time in the middle of the simulation processing by storing the transit of a model generated in the simulation processing stage in parallel with the simulation processing. CONSTITUTION:According to the progress of the simulation processing, the simulation model stored beforehand is changed one by one, and in such a stage, whenever the model changes, the internal time of the change and the contents of the change are stored into a stage change memory table. When the necessity of a model correction and a re-simulation is generated, the contents stored at the last of the state change memory table are read, the time is replaced with the present internal time, and by repeating a returning processing, and the simulation is returned to the desired internal time. Thus, the simulation processing can return to the one at the arbitrary time in the middle of the processing. |
