ABSTRACT:
The disclosed hardware and software co-simulator can execute two simulations effectively between two simulators each for executing simulation independently, by eliminating the idle times for waiting the execution end of the opposite simulator. The co-simulator is constructed in such a way that the time data generated at which the events transferred between a fist simulator and a second simulator occur can be extracted by analyzing the simulation data; and the expected occurrence times of the events to be transferred between the simulators are previously indicated to each simulator on the basis of the event occurrence time data.
