Abstract

Disclosed is a method that guarantees that the minimum number of physical device computations are performed at a given time in a logic simulator/physical modeling system. The disclosed method also assures that the most current set of input values are presented to the physical modeler. The procedure outlined utilizes the queueing theory readily available in most logic simulators. For each value appearing on an input to the behavioral shell of a physical device, that input value is queued in a special buffer known to the behavioral shell. In addition, schedule a device computation if and only if none has already been scheduled. The device computation will be placed at the end of the queue for that time.
