PURPOSE:To reduce the volume of a message and that of processing and to speed up simulation by transmitting a dead lock message to which the final time at which an output value is not changed inspite of a change in an input to a gate is applied as a reset time and advancing pin time up to the reset time when the message is returned. CONSTITUTION:A dead lock message(DLM) transmitting part 1 generates and transmits a DLM to which the final time at which its output value is not changed inspite of a change in the input is added and a DLM receiving/ propagating part 2 receiving the DLM updates the reset time added to the DLM, transmits the updated DLM, and when the DLM is returned, the pin time is advanced up to the reset time. Consequently, the volume of a message and the volume of processing in a processor can be reduced and simulation can be rapidly executed. |
