Abstract
PURPOSE: To shorten the simulation time and thus to increase the simulation velocity by executing the simulation in parallel for more than one unit of the gate.
CONSTITUTION: Main memory 200 which stores the information of more than one unit of the logic chart, the state chart, etc. indicating the logic arithmetic function for the subject gate in the subject circuit which performs a logic simulation plus CPU1 which carries out the pre- and post-processes for the simulation process based on the normal program are connected to logic simulation processor 400 as well as to input/output control part 300 which controls the input/output for the computer system via system interface 500 which carries out the interface for the information. Then an order for simulation process is prepared at the specified area of main memory 200 to give access to processor 400 so that the simulation may be carried out in parallel for more than one unit of the logic gate which can be executed at one time on the invent table via processor 400 and the information prepared at CPU100.
