ABSTRACT:
Event driven logic simulator for partial simulation is provided. An event storage has an event attribute storage section for indicating whether an event is preset before the execution of simulation by the operator. The node information storage has an event propagation flag storage indicating whether or not an event which has occurred during the execution of simulation will be transmitted. When the event propagation flag is off, the content of the event attribute section is determined. When a section indicates the event is preset by user, the event is propagated. Otherwise, the event is skipped. The operator can inject a signal pattern into a node by setting the event propagation flag of the node off and by registering events for that node representing the input signal pattern.
