Abstract
Event packets are input to an event handler both in a scheduling phase and in a dispatching phase of an event scheduler. In the scheduling phase, EVCNT of a device of an occurring event is counted up by 1, and in the dispatching phase, EVCNT of a device of a mature event is counted down. In the dispatching phase multiple events are detected based on the EVCNT. If an old status of the top event of the multiple events is equal to a current status of the device, it is decided that event-outstripping has occurred, and events are cancelled. If the old status is not equal to the current status, it is decided that a glitch occurs, and events are modified according to a given mode value. Since the event handler can be implemented by a simple combination logic unit, acceleration performance of a logic simulation accelerator is not adversely affected.
